The regulatory bodies aren't specifically discriminating against smaller vehicles, they're discriminating against vehicles that haven't proven safety to passengers in crash tests acceptable to the FMVSS. The vehicles may or may not also be missing mandatory internal safety features like airbags in all the right spots, etc.

If Chinese EV manufacturers put their vehicles through these tests, include all the mandatory features, and strip out the forbidden telemetry (certain manufacturers are banned in the US for reporting to the CCP- most notably but not exclusive to Huawei) then they too can be sold here.

If anything is preventing Chinese EVs from the US market, it's almost certainly their electronic components.
