How would you feel about Jaegers being given customised weapon payloads? I was thinking of switching out the Dragon's fit a little to maximise the effectiveness of its smaller power core.

Weapons I was considering would be:
[indent][b]S-11 Pulse Launcher:[/b]
[indent]A stripped down version of the [url=http://pacificrim.wikia.com/wiki/I-19_Plasmacaster]I-19 Plasmacaster[/url]. This weapon makes use of Mako Mori's upgrade designs for the Plasmacaster to create a scaled-down, rapidly charging rifle version for use on smaller Jaegers. While not as powerful as the I-19, typically delivering only one third of the hitting power, the S-11 only requires a three second charging period before firing. Its smaller capacitor system is extremely limited, only capable of firing a single shot before being fully discharged and requiring upto 73 seconds before reaching firing potential once more.[/indent][/indent]
[indent][b]WMB-H-118 Harpoon Warhead:[/b]
[indent]An upgrade to the [url=http://pacificrim.wikia.com/wiki/WMB2x90_Anti-Kaiju_Missile_Launcher]AKM[/url] which replaces the explosive warhead with a pronged spearhead designed to anchor itself within a Kaiju, allowing a small Jaeger to trap the target while larger, more heavily armed units close in for the kill. With a retractable polyduranide cable system the Harpoon can be recovered and reused in the field without requiring return to base for reloading, but due to the space requirements of the cable storage and motor system only one operational device can be attached to a single-pilot Jaeger, fully replacing its standard WMB2x90 package.[/indent][/indent]
[indent][b]WMB3x30-P Anti-Kaiju Plasma Launcher[/b]
[indent]Lacking the chassis space to fit the full sized WMB2x90, smaller Jaegers were refitted with an upgraded plasma warhead system, allowing for greater long-term damage potential to their targets while using fewer individual delivery systems. Upon impact the warhead begin a cascading plasma reaction, which remains in effect for upto 20 seconds after delivery, causing extensive internal damage. While proven effective against most targets, the WMB3x30-P only uses four launch tubes, typically mounted as pairs either side of the Jaeger's chest, each equipped with three rounds for a total of twelve round per system.[/indent][/indent]
[indent][b]V-PI EnergyCaster[/b]
[indent]The predecessor to current Plasmacaster technology, the [url=http://pacificrim.wikia.com/wiki/Coyote_Tango#Features]EnergyCaster[/url] instead used shock burst of electrical power to overwhelm a Kaiju's nervous system, much in the way a tazer would incapacitate a human, but on a much larger scale. Able to function in five different modulations, each requiring a progressively longer perido in order to fully charge, the EnrgyCaster can incapacitate a target allowing more heavily armed Jaegers time to move in for the kill. Repurposed for use on the newer, smaller single-pilot Jaegers this weapon can act as a highly effective disruptive weapon system.[/indent][/indent]
[indent][b]Gatling Chest[/b]
[indent]Designed as a cheap and easy solution to longer ranged combat with the Kaiju, the [url=http://pacificrim.wikia.com/wiki/Romeo_Blue#Features]Gatling Chest[/url] mounts severeal high calibre cannons in place of the more traditional AKM system, allow for more peresistant, if far less damaging attacks. The Gatling Chest is mianly used for holding actions, where the priority is to delay the target rather than destroy it, such as when evacuation procedures are ongoing, heavier Jaegers are moving into range or targets are required to be captured alive for study and analysis.[/indent][/indent]
[indent][b]Rail Gun[/b]
[indent]Originally designed for conventional warfare the [url=http://pacificrim.wikia.com/wiki/Wolf_Queen#Features]Rail Gun[/url] was quickly repurposed and redesigned to function as part of a Jaeger's arsenal. While potentially capable of delivering grievously crippling blows to its targets at long range, the Rail Gun has very limited ammunition (12 shots for twin-pilot Jaegers, 9 for single-pilot models) and requires absolute stability to achieve a successful hit, making it an unpopular choice amongst most Jaeger designers and pilots.[/indent][/indent]
[indent][b]Wave Laser[/b]
[indent]While lacking the hitting power of most munition based and plasma weapons the [url=http://pacificrim.wikia.com/wiki/Redflag_Horowitz#Features]Wave Laser[/url] is easily controlled and targeted due to its persistent attack style and long battery life. Capable of being set to a variable range of focuses, from wide wave dispersal to precision cutting beam, the Wave Laser is a highly adaptable battlefield tool, if not the most effective weapon.[/indent][/indent]

Most of these were culled from weapons seen on models of Jaeger other than those shown in the film.
