Probably not a popular suggestion with the PvP crowd for a store item.
How about adding a Trammel rule set token to the store? It would be a use once item that permanently makes the character use the Trammel rule set in all facets and shards. The character can not be harmed by other players (ie Reds) and can not harm another player. The character can play the champ spawns in Felucca but does not get the big prizes. They can recall from any place. Price the token at say $100 so only serious people would use it.
