If you want to solder a 68882 FPU to your MB, simply you can. It will working. (of course if you have some knowledge how to do it.) But as mentioned above, it hasn't got much benefit without extra ram. (which if we speaking about the 1200, is Fast ram.)This is true for the default 68020 in your amiga. If it has some, it will do its job more faster.
Maybe Some 3d games, but mostly apps like Imagine/lightwave can use the fpu.
