I like the wipe skirt that is printed when you activate Ooze prevention, but it only prints using the first nozzle, and when it switches to the second nozzle it just starts printing without first wiping it. Making this skirt composed of a perimeter for each nozzle would make it possible to wipe each nozzle just prior to printing. For layers only composed of one nozzle , to prevent unnecessary tool changes, all of the perimeters would be made using the active nozzle.
One other thing to consider for this, is that when the tool change occurs the newly active nozzle is moved outside the skirt. Unfortunately, depending on your setup, this can result in the drooling previous nozzle sitting on your part while it cools. Running the first nozzle around its perimeter quickly (preferably with the cooling fan on) before switching to the next nozzle would help with this, as would making the slicer aware of the configuration of nozzles (currently an option, but not if firmware handles it).
One other idea, rather than making n loops, which could be quite a waste of filament for larger prints with many materials, a single loop broken up into n sections could be used.
