I'm looking to Mech out my current Ork counts as IG army but I don't want to buy two more Chimeras, so I'm looking to convert.

Right now my Infantry would go into normal Chimeras but I have a CCS and a PCS, I think their rides should be a little nicer. So I'm looking at vehicles to be a starting point. Something about the same size (I don't want an advantage/disadvantage by size changing) that can have the right guns on it, in this case Multi-Laser and Heavy Flamer.

Any ideas LO? I looked at Trukks but that seems like a crappier ride, not a more commanding one.
