Thanks.

But, I'm not doing it, I'm just curious.

Would the (backwards) lens being mirrorless matter?

The lens is a lens - it doesn't matter for what system it was designed for. It only matters if you can control its aperture using it reversed. For some lenses with electronic aperture control the aperture can be fixed to a desired value (as I described in my first answer).

And if you stay within the same system, you can use (expensive) retro adapters to use lenses backward with fully automatic aperture control, see e.g. here: https://www.novoflex.de/en/products-637/macro/reverse-lens-adapter-canon-eos.html

Hope this helps!
