Seriously though I would recommend removal of all loose substrate, ProBlock alkyd primer sprayed on the brick with a 517 tip (proper cleaning of your pump will not affect later latex usage), metal studs, 1/2" drywall, PVA latex primer, and finish with a latex topcoat.
Or:
Remove all loose substrate, spray the brick with ProBlock alkyd primer using a 517 tip, skim coat with green top all purpose joint compound (maybe 3 skim coats then texture if you want), roll on (3/4 nap) ProBlock alkyd primer to seal the mud, finish with a latex top coat.
