haven't tried that, but i do ferment saisons with both saison sacc and multiple brett strains together in the primary, and am very happy with the results, when fermented relatively low temp. you can search around HBT and find 1000 views on whether you should have dedicated equipment for brett, i don't, i clean my kegs well. i do keep one plastic fermenter just for brett, and a dedicated autosiphon, and everything else is shared.
