You can do something similar to this:

Easy, fast and cheap. You will have to design your own board, due to
special power pins allocation.  If you never work with smd, ssop can look
difficult, but it's not so. Of course, soic is easier, but ssop feets
perfect and is affordable enough to be hand soldered. Qfn and others are
much more difficult to be hand soldered. Only need to add programming pins
for icsp and you have a direct replacement board.

you can probably make a plug in module which is no larger than the 20 Pin
DIP package.
