The NiCd cells are vertically PCB mounted, so I'd like to try to fit the
buttons in their place.

Forgot to mention that one type is horizontally mounted, and quite
space-constrained (I have about 8-9mm diameter by 5mm height to play with,
so I'm looking at something like an SR41 cell). It might be possible to
make a land area for a negative electrode, but there's nothing to solder a
positive electrode to that'll give mechanical stability.
