To solve the FF page wrapping problem, I wonder if it would work to double-map each 6502 page to x64 host pages side by side. I assume the word read at FF would straddle the two mapped pages effectively reading the second byte at 00. You'd have to map to host page boundaries of course and probably offset all reads/writes to the end of the host page at $3F00.
