Hi Jeffrey! I also started some years ago my own project for converting a 1451 into a 2031LP, of course with switchable kernel and maintaining both ports. A daughterboard is quite an easy thing to add to the 6522. However I realized that 1541 format isn't write-compatible with the 3040/4040, so at least for me it wouldn't allow me to share the same disk (well, share in read only mode, yes) between my PETs. Converting a 1541C is way easier anyway, you don't need a ROM adapter, just a 27256 and a switch and you can re-use the 27128 socket on the 1541C motherboard.
