I can't see why a gap should be filled just so a (sorry to say) lazy person can go from PvE and directly into high PvP. If you want a slice of the pie, get in queue and change your knife for a spoon.
Blizzard gave you the gift of changing valor to conquest in Cataclysm, they have removed it for now in Mists of Pandaria, but it'll surely return as it helped the PvE'ers into PvP by allowing them to trade points. If that returns, then I don't mind if they trade points to get gear.
And the reason PvE gear players many times stood better chances against PvP geared is because of the greater damage done, but you would still be an easy target and therefor taking down first. It's all about appearing in the right outfit.
