Can the AI be Friendly if it creates human-comparable minds with abitrary nonhuman values, provided the resulting homunculi are not, themselves, significantly hostile or in any way self-improving?

If so, I think there's a simple fix for this: have the AI give everyone a volcano lair (or equivalent) and two dozen catgirl minions. That puts all humans solidly in the top 5% of humanoids, which is a nice status kick; they can still compete with other humans for the last few percentiles, but there's no real risk of ending up at the bottom of the heap... unless you're into that kind of thing, which is a whole other issue. Catgirls are set up with desires for pleasure and status comparable enough to humans that they can put up a good show of competing, but they never really outshine their master, disappointment or humiliation never permanently discourages them, and various other safety measures could be fully integrated into the design.
