Since it would be unwise profit-wise for Riot to implement a skin trading system, what if there was a way for Riot to guarantee profit despite allowing trading?

Proposal: Allow skin trades but require both accounts (with a minimum level requirement) to sacrifice some Radianite Points when trading (this could either be a fixed amount or an amount that scales with the value of the gun, including how many upgrades it already has).

This way, Riot guarantees either profit (players have to buy Radianite or the BP) or guarantees extensive gametime (players have to grind Radianite out of free pass) while pleasing the community.
