I'm not sure if individual towers will work, because it negates some of the Jenga-narrative cohesion. If there's individual towers, then the aspect of making personal moves that might result in the death of others is negated. It also means you can't "jump on the grenade" and drop the tower to save the others.
There are multiplayer online Jenga options, like the Andriod app. I haven't tried them myself, but it might be the best direct solution.
In the Jenga app you can actually move the pieces however you want until you remove one.
