Most frame pumps fit under TT Some attach via WB bosses to DT or ST. I'm unaware of any which easily fit to seatstays. It's probably a good idea to not mount one near rotating wheel, for reasons you already know.

I've owned 2 of your 3 listed pumps, and they generally work well. I suggest you also consider Park Tools adjustable length frame pump, and the Lezyne micro drive.
