2005 MR Vader - Conversion to Neopixel Build

My neighbor came over the other day while I was tinkering with my light saber build and said he had something to show me. He brought over his MR Vader saber with the string blade. He asked if I could make it look like one of mine. I was thinking I could do an NBV4, neopixel blade, 18650 battery with a black momentary switch on the plate with the two thumb screws.

Does anyone know if the MHS chassis from TCSS would work on this hilt? It would make for a pretty simple conversion. Thanks.
