Always thought it was a bit of a bastard what they did with that girl, making her hold the horse with the bomb on
If Napoleon is blown up, then he is First Consul rather than Emperor, and I guess the Revolution looks for a new First Consul - whether he comes from the ranks of the existing Consuls, or the Assembly, or from the military I don't know
Presumably the plotters hoped for a Bourbon prince to descend to rise up the royalists, so whoever gets the job would have a civil war and an invading army on his hands
