Why not just have three guys 6'10" or higher, and two PGs?
Since you can play zone, the three big guys would, essentially, prevent any dribble penetration in the half court. They'd have position, get all the rebounds, and would relegate the other team to jump shooting. Since you'd have, essentially, three rebounders, and three shot-blockers, the guards could gamble every possession, and force the other team to either play back to the basket, or fire up threes.
On offense, the bigs are great picks for the pick and roll game, and can set giant screens for the guards. Obviously, you'd want tall guys who could score facing the basket - but I think that's available these days.
Your PGs would have to shoot all your 3 pointers - but so long as your other two bigs could hit mid-range shots, they'd have an easy enough time getting open the Defense would have to be in the paint all the time. A super athletic team might be able to take the ball more often, and score more points on the break - but so long as you scored more often than not, you'd be playing half court ball most of the time and, more often than you would otherwise, ending the defensive possession with a defensive rebound.
Come at me bros.
