Then you need to take the MIDI drum strikes from Garage Band into a VI running on Pro Tools that can do that...

Pick a Drum VI and go start working through some tutorials on how to use it. DUC is not the place where you can get handheld though using some VI or plugin.

You've got XPand 2, as far a I know that does not do multi-output (it also likely just not the drum VI most people want), but you can manually put different MIDI on different instrument tracks with separate instances of XPand 2 on each instrument track.

EZ drummer may be a better drum VI to start with and it can do multi-outputs.

You need to pick a VI and go start working though how to use it. Expect to spend an order of magnitude or more time learning how to use that VI than using Garage Band. And after doing that you might ask yourself why you are starting in Garage Band at all

Like with any DAW you should be able can run multiple separate instrument tracks of the same VI in Garage Band and route/process them however you want. Which may let you do what you are talking about all in Garage Band.

You may be far over-complicating all this and getting yourself in way over your head. Start by looking at EZ Drummer on Pro Tools and see if you want to even go there.
