I'm all for cooperating with other groups and the like, especially since the current system allows for multiple groups to share an ID. I don't think it would make things too difficult, especially since part of the "lore" if you will, for the RKS is that they were just one particular branch of the State Police, not intending to represent the entirety of the state police "in lore".
So anyway it'll be neat if the other group is still around and if the two groups could fly together and such, if I can manage to revive the RKS at all that is.
