Kit to upgrade to neopixel?

Looking for help to find a kit to get this hilt to run a neopixel blade. It is a cheap saber I purchased on AliExpress when I first started looking into sabers. I really like its dimensions/weight and how it turned out after some painting and weathering. I've been hunting for a neopixel kit where I could bolt in the recharge port and switch manually without having to purchase all individual component and solder & wire it myself. At this point I'm thinking learn soldering or have it commissioned, but maybe someone has seen a kit out there that would fit this specific case.

A few constraints:
- The switch and recharge port are in positions where a standard LGT kit chassis won't work. (Switch is closest to emitter, with recharge port about 3/4"-13/16" lower, center-to-center)
- The inside diameter is closer to 7/8" rather than a standard 1".

Any input would be greatly appreciated.
