Here's my Capellan/Kuritan-inspired roster.

5,349,575 C-bills - Catapult CPLT-K2
(Breaking the mold of the Catapult, this House Kurita model removes the LRM-15 launchers and replaces them with two PPCs, allowing the Catapult to act as a direct fire support 'Mech and take a more active role in front line combat. The 'Mech mounts five additional single heat sinks to help dissipate the added heat from the PPCs and two Machine Guns to deter infantry attacks. Space is made by removing the jump jets and two of the medium lasers.)

5,212,800 C-bills - Grand Dragon DRG-1G
(Arguably the original Grand Dragon produced in 3024, this 'Mech is itself a variant of the original Dragon. The 'Mech is armed with a PPC, LRM-10 launcher, and a trio of Medium Lasers (one of which mounted to the 'Mech's rear). It is also only capable of achieving a top speed of 86.4 km/h, as it employs a standard fusion engine due to the technical imitations of the 3rd Succession War.)

2,161,250 C-bills - Regulator Hovertank
2,161,250 C-bills - Regulator Hovertank
2,161,250 C-bills - Regulator Hovertank

Remaining - 3,153,875 C-bills
