The use case is certainly valid, but the suggestion is not (sorry). What really needs to happen is that all the transmission plugins get a rewrite such that they aren't self-contained or overly complex.
Ideally, the transmission plugins should just be able to feed torrents, get a list of torrents based on criteria and manipulate existing torrents. What we have now is a mess.
No one on the team uses transmission though, so we currently don't have any incentive to undertake such a major rewrite. We'd happily review any and all PR's on the matter though.
