What about letting 1) and 2) to finish, as if everything went fine and then, as a last and desperate attempt to avoid having a profile with no ports available, check if there's a better option and switch profiles if needed? That's the "hack" I've been experimenting with lately in this device (notice that we use PA 5.0, but an stable release, not the trunk), and so far seemed to work fine, although I'm not 100% it's a totally broken or not.
