Yes, in theory, as Jack explained. Ball-string friction probably does have importance during the snapback phase, when the mains have to "re-bite" the ball. Very thin crosses will reduce the angle of the weave which should reduce resistance to the mains sliding and snapping back. So a thick main (good ball-string friction) + thin crosses (low interstring friciton) should be good for spin.
On the other hand, very thin crosses and mains would reduce the angle of the weave even more, and as long as the thin mains provided a lot of friction with the ball (Cyclone 18 or similar, kevlar 19) this might be even better.
But in terms of reducing the angle of the weave, the best way, obviously, is to use a more open pattern, and specifically to reduce the number of crosses. Which is what Wilson and Prince are doing in 2013. (And probably everyone else too.)
