Motors primarily -- for that long/fast of a prop on 4S you'd need either a lower kV or a MUCH beefier motor (and then the ESCs would need to be upgraded too). If you were to find a similar motor in a 1700-ish kV, you could get away with regular 6x4.5's . . .
. . . but isn't this the tail wagging the dog? Props are cheap, and on multirotors, consumable. Motors, not so much. Being able to share spares is nice, but if you're flying with any frequency, you'll be buying enough that it probably won't help. It's your money, but I'd size the motor for your need, then get the prop that matches.
