I don't think so, elimination of the quaternary amine is hard and needs extreme temperatures or conversion to the hydroxide salt (Hofmann elimination), but that won't yield scopolamine
The conversion of scopolamine to its butylbromide isn't easily reversible, I'm afraid. It may still be deleriant if you take enough of it either by brute force or by dealkylation in the liver by CYP enzymes ... after all scopolamine is really potent, in the single mg scale.
