Grant me the powers of rendering any opaque material transparent and vice-versa.

What is the most accurate way of translating the term vice versa into Latin within the context of the following sentence?

Grant me the powers of rendering any opaque material transparent and vice-versa.

This is my attempt at a translation using what I found for vice versa in a list of Latin phrases I have.

Da mihi potestatem reddendi ullam opacam materiam perlucidam et vice versaversa vice.

Vice versa is Latin already. It's an ablative absolute meaning something like "in changed succesion" or thereabouts. I believe it's a modern term though, but I'm not sure. Another option could perhaps be e converso.

Thanks, to avoid confusion I will probably use your suggestion of e converso
