There may have been a few things like that tried here at some point before...can't recall specifically...
This will likely stir talk of the "package", and how people can't be trusted to live up to their end of a deal etc.
I myself think it might be a valid idea and raise a bit more traffic in here, perhaps a trade system incorporated too?
I think that on account of former events though, the senders consider only a cash on delivery system, protects both parties....unless someone were to, oh, say send a box of rocks instead of the described item, at which point all they could do is get reported and barred from future transactions.

See, it's pretty difficult either way.
I myself wouldn't mind having a look.
