Although Sno could impersonate many Gods, Ammon was the only suitable choice. Roselle himself needed time to resurrect, and Klein needed time as well.
But beyond that, the most important point was that Sno had no way to obtain the Fool's or Black Emperor's authorities and power.

As for power, the combination of A Foot of Rod and Maxwell's Demon was enough to provide spiritual output at the Sequence Zero level.
