In-Guild only player auctions

Just a thought but how about adding a feature that allows you to also sell a player privately within your guild?
Obviously there would be restrictions on players you can buy not exceeding your level at the time.

Just think its a cool idea to assist smaller players in your guild and allow them to grow quicker..
I like this idea!!!
It's been requested before, but to keep the leagues fair, they have to cap the players' abilities to their league level, which makes this idea impractical.
It will also increase the gap between real money spending guilds / players and the non spenders.
