Personally I think it would be great for the US to have a quick flanker with a decent gun, we already have the LAV chassis (as the LAV-AD) and we already have weapon systems such as the M242 (as the M3(A3) BFV) and the TOW launcher (as the M901), surely it’s not too hard to stick them together for LAV variants (LAV-25 (or personally an ASLAV), LAV-AT)?
Personal requests would be the Modern TOW launcher (LAV-ATM) and the mortar variant (LAV-M)
