...I would think that you could resuse the existing battery tabs in the 3in1, and solder them to a new bare CR1220 battery.
That's exactly why I mentioned the pre-tabbed batteries - because reusing the tabs from the original battery is nearly impossible. You might as well just try to solder wires onto either side of the battery (which I did once with a SuperCard, it worked but it was a mess).

...Maybe even de-solder the existing tabs instead of prying them off with a blade eliminating the chance of breaking the tabs off accidentally.
The tabs aren't actually soldered to the battery, they're "punched" into either side. Which would be hard to replicate without the proper tool - and I don't know what that is.
