well, you can't put yoda sids, and maul in the same room either, give them 10 minutes in the temple alone before you send in the soldiers, and they win. They don't have to control everyone's minds, just those in charge, and in a huge temple, there are plenty of opportunities to pick off small groups of soldiers. Being highly trained, there is no way these soldiers all stay together, because that would be disaster, as yes, then sids and yoda could cause a disaster that would kill them all, so yoda and sidious and maul won't have to fight them all at once.
the odds are kinda dumb here, but i would give the trio a chance, after all, if the force is with them, they can overcome impossible odds (obi-wan killing off those 4 magna guards after he and anakin each struggled to kill one earlier in the movie)
i'll give it to the trio
