For those that haven't done the Moonfire Faire event yet, you get a sentai-style suit (Phoenix Riser Suit) as a reward. You get a helmet too, but I'm specifically interested in something the suit does: wearing glowing MNK weapons, such as relics like the Sudarshana Chakra Anemos, as well as other ones like the Makai fists, will leave only the external "glow" the relics output over the suit's gloves, creating a very powerful look. Other weapons (such as the Fists of the Fiend) will have parts of the weapon showing, like the outer top of the fist protruding like a sort of external power kinda thing. It fits well.

My main suggestion, though, is to allow MNK to be able to buy "Emperor's New" versions of Relic glows from the replica vendor. The idea is that they'd be able to glam the relic glow over any normal gloves- or just bare fists/nails!- and have their specific style while retaining the unique shine of any relic they've obtained. Some relics, like the Heavensward ones built around the larger weapons in particular, would need their glow made to fit a little different than usual, but ones like the Sudarshana Chakra Anemos and Pyros Knuckles would likely fit right in.

For visual reference's sake, here's how the Sudarshana Chakra Anemos and Makai Fists weapons look on the Phoenix Riser Suit:
