My advice would rather be to:

1. Make 3 new wow folders
2. Download Macaroon
3. Figure out how it works
4. Write everything with the macro function, that way its saved localy.

Now you can have complete different setups for anything you wanna do!

Ive done it this way and i can switch from a full pvp setup (4 shamans) to a full pve setup (protadin,3 shamans and a hunter) or i can simply play with my hunter,shaman or paladin solo.

All key maps are different and all i need to do is pretty much to restart wow!
