nasmuch as you relate your sexuality to your politics, do you think your framework would be good for - or is at least undervalued as a personal option by - the wider population

Yes.

(and/)or are you more concerned that feminism will seek to make your lifestyle choices untenable?

Not really. Far too few men are pursuing it for it to be a viable source of power once broken down. And my social circle has an anarchist bent already. It may become endangered by families in general being outlawed but that is decades away even in the worst case scenarios.

(Also, whenever I need to raise my subjective status relative to yours I'm going to think of you as a Gorean. Fair warning.)

Read up on them. So far Goreans are an interesting subculture but seem to be bad at political theory. Not that it much matters since politics is not how they prosper.
