So would I, but my M5 now feels too small. The RP is about the same weight but larger and feels better.
I agree that the RP feels (much) better when held in my hands.
However, you can't use the RP without a lens on it. And when you place RF or EF glass on it, it won't be about the same weight as the EOS M5 coupled with EF-M glass. Not even close.
