Plenty of non-RP players play on RP servers. As long as they respect the RP players and do not try to grief or otherwise disturb the RP it is not a problem.
Looking at the log in figures suggests that all the current RP servers run at about 20% of logins - enough to support one RP server if Turbine wants to have broadly even server load. That leaves an awful lot of players currently on other servers to be willing to move to justify two of them. I'm just playing devil's advocate here - I really can't see a situation where enough players would want to play on an RP server to justify having two, particularly once language restrictions come into play.
