Place amethyst crystals on top of note blocks to extend the note

I’ve always wanted to use longer sounds with note blocks and I think I’ve thought of a fitting way to implement that. Amethysts are far too musical to not be used with note blocks in some form, so I think that placing an amethyst crystal on top of a note block will “resonate” the note and the sound will continue playing, as long as the note block is powered. I think that each stage of crystal should be able to continue a note for up to 15 seconds per growth stage. So, 15 seconds for the small bud, 30 for the medium bud, 45 for the large bud, and 60 for the full cluster. If you try to play a note for longer than this the crystal will resonate too hard and shatter. The reason there is a limit at all is mainly to stop infinite noise. If this was implemented it would add another use for amethysts, and give players the choice to have long or short notes when using note blocks, with even more control if you’re careful with the length of the Redstone signal.
