Would like to see a macro zoom lens

The problem is I have 3 macro lenses 50, 70 and 100, I pick the one I want depending on the relative size of foreground and background I want, I'd like them to be one zoom lens.

Yeah, I gathered all that from the original post.

I feel like large aperture macro lenses aren't very useful because you can't get anything in focus at f/2.8 anyway,

And yet, somehow, I do.

so you're mostly using them at like f/8 or lower, so what's the point of having it be f/2.8?

Resolution. At f/8 you're bleeding out the resolution paid so much for with a 30, 40, 60mp camera.

When focus or DOF is a problem, you use focus stacking. I do a lot of work with a Zeiss 100mm f/2.0 Makro Planar.

controlled lighting as in my scene is always the same brightness, I always shoot at f/11, and with the lenses I have, that have relatively low light loss at macro ranges, I don't have to change any settings when I want to get a closer shot, most of the time. Where as a lens that has lots of light loss at macro range, I'd have to start changing settings whenever I want a closer shot, which is annoying.

Ah. Then I wonder what the focal lengths of your lenses actually are in the macro range. A "unit focusing" macro lens obeys the inverse square law. By the time you extend it to 1:1 you're down two stops. Floating element (internal focusing, rear focusing, etc) designs "zoom" the lens to a different focal length to reduce extension and aperture shrink, but you pay for this with shorter perspectives.
