When I have more time, I want to make a whole series of “this monster for this level for this party size” for some of the most quintessential monsters, like you described, but also a few quintessential mixed units for major antagonist encounters, like 2d6 goblins, 1d6 wolves, 1d4 bugbears, and 1 hobgoblin shaman for a 5th level party is a good boss fight. I’ll try to do a version two of this over my holiday vacation.
