Can I replace rossignol fks 180 afd to make them gripwalk compatible?

I recently got a pair of rossignol fks 180s for cheap and I have heard they are basically just a clone of the pivot 18s. I have also heard that you can simply replace the afd in old pivot 18s to make them gripwalk compatible. Would this still work with the 180s even though they aren’t pivots?

I really want to use these bindings so if that won’t work for whatever reason then should I swap my boot soles to alpine or would that create other problems?

If I can’t use them safely then no worries, I was just hoping to save a few hundred on new bindings

any help appreciated, thanks.
