Can I "combine" accounts? Or at least transfer the Coins and Unlocks?

Question sort of says it all. Can this be accomplished? I have two accounts that I know all the info to, but I'd like to have everything on one account (with a unifying email).

Can this be done? Can I have characters transferred from one to the other? Or could I at least transfer the Legacy Purchases and coins?

Would like to sub, but everything is kind of wonky.

Thank you for your help!
