I'd guess that, due to stingyness factors, the only way you'll see those items again is by re-upgrading them. The items'll still be there.
I doubt the accounts bods could be bothered to add like an hours worth of gold time onto your account just so you can transfer some items. And if they're items like mithril and other alch stuff, or event items, then...Hah, good, i hope they stay there out of everybody's reach and out of normal player's ways
