The bolt mod and swapping keys around are two separate things.
But, the answer to both questions is yes. A Model M is the best donor for everything, really. (Also, vertical keys, like numpad enter, grab the key and stabilizer from a Model M, and use them anyway, if you're taking things apart, even if you're keeping that part of the layout the same as before.)
(The Model F assembly is done by interlocking two steel plates, with everything between the plates. No rivets. But, if you want to make things stiffer (really only useful on 122-key boards), there are ways to do a bolt mod.)
