Here's my take on the Wolverine, possibly bending requirements a bit:
First, a fission engine. Because why not. Limits speed to 3/5 though. Jump capacity isn't provided by jets but mechanical jump boosters. You don't oppose flinging a 55-ton 'Mech with radioactive engine into air with springs, do you?
Armor is industrial-grade plate, 13.5 tons of it.
Armament: Heavy Rifle with two tons of ammo, a vehicle flamer with one ton of ammo, and four rocket launcher 10s for some endurance.
