I've always wondered why trucks don't use series-hybrid like locomotives. Last I check, AC-AC locomotives from GE were hitting 90%+ efficiency.
Not only do we have multi-motor redundancy like you mentioned, but we can tune the IC engine for a single (at most 2) operating points. It'll be a lot more efficient, and the emissions system a lot more reliable.
If I really want to dream - why not have traction motors on the trailers in the future? This works for both series hybrid and full EV drive-train. As someone who's chain up on BC snow passes, I would've given anything for an AWD semi combo back in the day!
