I may possibly be interested, I more traditional in my appeal to things though. I don't often do Magic/Mech combo Rps or universes really, though I am heavy into Star Wars ironically. XD 

I do feel though, if you don't pan out with the use of Mechs or a Pilot/Mech Class system, there is always the off-chance you could do a resemblance/similarity class. For example, if the idea doesn't pan out and you want to go more strictly traditional with Medieval/Fantasy genre styling, you could always implement a sort of "Golem" class/race, or things of the like: Golems, Familiars, Titans(Not the archiac Mythology variant, although that would be hilarious. XD), etc. 

OR

If you would prefer to go a more Futuristic direction with the Mechs being more of the Focus, you could have it setup to be Mechs and Mech Squads. I.E. Mechs of varying sizes and designs as well as players with weapons and combat benefits the Mechs don't gain, such as having players who use non-Mech classes being able to access a wide variety of Support/Support-Combat abilities similar to hacking, air-drops, player-VSplayer Non-Mech combat, Mech Repair, Mech Sabotage, General Sabotage, etc. 

These are just my input, I will be watching this to see how it pans out and eventually decide whether I want to join. ^^ If you would have me, that is of course.
