Thanks for Your info. and commitment.
I've comed to realize that this type of "upgrade" seems to risky, if possible at al nowdays, and that it's probably a much better idea to trade in either our Prius PHEV 2015 gen 1 for an gen 2 or trade in both our gen1 and our Prius+ 2017 for a new RAV 4 PHEV (can just afford one car in that case).
Like or cars though so there is a lot to consider.
