Extending beacon effects with amethyst crystal

The title explains it well enough. Beacons have always had a small range and adding layers meant stronger and/or new effects so I don't think adding a new layer for extended range make any sense but instead by taking advantage of the new amethyst crystal we can achieve this goal on top of that there can be a way for a shorter range, higher tier effects (considering how lenses could be made out of amethyst that concentrate light it makes a lot of sense )

So let me know whatcha think?!

EDIT:after a bit of tinkering around with the idea here is what I came up with : (AB=amethyst block TG=tinted glass)

Purpur-----Ancient debris-----Purpur

Ancient debris-----AB/TG-----Ancient debris

Purpur-----Ancient debris-----Purpur

This way it isn't cheap and it gates it behind end and finding of ancient debris (also amethyst block is for extending and tinted glass for diminishing)
