I actually just heard back from Merge today and was surprised to find out you CAN transfer your rakeback between skins if you've been inactive on the skin with rakeback for 60+ days.
If you have a rake back account on Lock you get the flat 35% rake back and none of the VIP promotions.
@Rizen - In addition to Aggro's question... When Lock begins to allow new U.S. player signups again, will the new players who have rakeback on another Merge skin be allowed the same luxury?

Provided they've been inactive on the Merge skin that has their rake back for 60 days or more, yes.
