most vtubers fans hate fleshstreamers, hence why they watch vtubers
Also audiences rarely overlap since people who watch fleshstreamers also hate vtubers for some reason
In general, collabs rarely translate to viewerships, even among women, so only do it if you think the collab will actually be interesting to watch, which in most cases it sadly isnt.
If they want to help you they can just raid you, if you see you can retain some of that audience maybe it will work
Also your GFE viewers will absolutely hate it no matter what so they will probably drop you
