I don't know still which emulator will be since I haven't ran the ones are available right now, I am checking sources

.
Today I think I may have some proof of concepts (screenshots) about it to make your mind

.
@lesderid roc summit is a great idea, but placing there the NPC's would be like... too poor isn't it? however I may start it on roc summit since is a small place where I can test out everything.
I will be working on everything right now
EDIT: I doubt this can be done with srevolution emulator since as far as I know the source code is not public, so I won't be able to tweak the things we have planned, however we will look further deeply on srevolution to check if it's possible to be made or not.
