Shouldn't mages learn spells faster if there's more mages around them to feed off of?

Basically the same premise behind bonuses for killing in groups of three, if there are 3 mages sitting around casting invis on themselves you'd think they could learn it faster (percentage wise). Of course they'd all have to be working on the same spell, and probably of the same guild.

Thoughts?

P.S. No, I'm not playing a mage now. Just came to mind and thought it made sense.
