Jung Ma will never be merged, it's the only one of it's kind.
BioWare is ''actively pursuing'' server-transfers, so don't count on that to help you out any time soon.
There's a dev-tracker post where they said they're aware of the low population problems and are going to wait and see if F2P fixes it.
In any case, no one's going to help you in any way.
You could do what I do, I play up to 2 hours on Jung Ma during prime time, because there's enough people to get my PvP daily done at that time, and spend the rest of my time on the Ebon Hawk.
Could just merge it with a high pop PvP server and put a RP tag o nthat new server. 98% of the rp server doesn't rp. I don't think it'd matter. Offer xfers to a RPPVE and a plain PvP.
Only problem is BW/EA don't know how to communicate or listen effectively to make a successful choice.
