The 16 bit 6502 is a wdc65816 - see http://www.wdesignc.com/

I got one in an old Acorn Communicator I was going to put in the second
processor board of my BBC Micro, but haven't played with it yet.

They are used in the Commodore 64 super accelerator -

Anyone for a C64 with 16 Meg RAM and a 20MHz cpu ?
You would have a lot more scope for software envelopes etc to drive the SID
chip.
