I have no idea if any of these guys are options, but here are the remaining in the portal who are power forwards or centers and top-500 according to 24-7. That's it. That is the whole list.

Enoch Boakye, Fresno St - 6'11, 250 - #471 - 7.5 PTS, 7.7 TRB
Pretty slim pickings. At this point some of the dudes above aren't much better than Onyema. What a shit show.
I would try to get DJ Burns since he is a grown assed man at this point and could be plug and play at Power Forward. Then maybe Duncan Powell since he has some state of Texas connections. But man, this isn't good.
