Is this before or after the events of the comics? If before, there's more than a few events from them that we could use to destabilise the village easily (as we are hopefully a bit smarter than the Romans ever were!) - Caesar's Gift and The Roman Agent come to mind...we could use Obelix And Co. too (my favourite Asterix book) but that would potentially take a lot longer.

If it's after those events and therefore the Gauls are savvy to all of these things, we could always be more pragmatic and just set fire to the village using an electric igniter jury-rigged from non-essential systems (like the directional light for No Consequences' spinning - it's not needed if nobody external is driving it!)
