Not officially, no. phpBB3 has not been released, and as such has no officially recognized MODs or styles yet.
The old styles demo cannot simply be repointed to this board, since the structures are completely different.
I don't see a technical reason why you could not have a demo phpBB2 board running, and point the styles demo there, but that is a decision for the Styles Team to consider.
