I don't think it's horrible, but I doubt its +EV unless your opponents CC'ing standards are v loose or they suck bad. 96o isn't strong in high card power or connectedness and isn't suited, so it really doesnt have much going for it. with 3-coldcallers you could likely be reverse-dominated, and playing one pair on some boards, while you have good relative position, won't be very easy.

SB 3-betting K4o against a standard button open is really bad. BB defending K4o, is at the lower end of what my BB defending range is but I think calling vs button steal is fine.
