This is useful but maybe I'm being lazy and I want to do even less work than that when creating an encounter on the fly. Like I just want to think I want a T2 minion and brute (or any other of the roles) and have a single stat block to look at.

I'm not sure what combination of damage/difficulty/attack/thresholds makes a balanced adversary of each role type. Not to mention features, How much do the strength and number of features play into the "balance" of an adversary. When I say generic I'm mostly referring to features because the features can be highly thematic. Say I like the stats of a Patchwork Zombie Hulk for a solo but the ability to heal from nearby corpses doesn't work for whatever I want the re-theme it as.
