Update on the 65816 to 6502 adaptor
I found a couple of forum threads (listed at the end) where the idea was discussed and plans were even made to build boards for Daryl Rictor's design but it wasn't clear that the design was ever tested. And the SMD version of the 65816 that the board used is apparently no longer available.
There was also discussion about the Ruud Baltissen design and reports that it worked for several people, although not on some systems which made use of some 6502 pins that it did not support. I don't think these limitations apply to the Replica 1.
I was thinking about assembler support and checked and confirmed that the CC65 assembler supports the 65816.
