You want to optionally drop the message in the transport? No idea how you'd
do that. Decision-making is done in the routers, transports do what the
routers tell them.

Can't see why you shouldn't be able to do that - have a redirect router
which has a data= clause that resolves to the aliased address if the
condition you want is valid or ':blackhole:' otherwise - this will then get
passed to the transport or devnulled which I think is what you want. No need
to involve user accounts.
