You should have no major problems operating a suitably adapted daughter
carded 68020 in a "68010 socket".

I've used both 68010s and 68020s in Amigas since 1985, and several weeks
ago operated a 68030 on the same machine.

There are commercially available cards facilitating such conversion, with
provision for 32-bit-wide RAM (static) cards attached "locally".

Software changes require enabling the cache(s) and cognizance of the
different stack frames.  Operating systems such as that on the Amiga handle
the different processors with ease, and Motorola publishes AppNotes detailing
these steps in the general sense.
