Does anyone know of any sequential shifters for the RalliARTs?

I looked for a bit but couldn't find anything guessing not since aftermarket RA parts is basically null

 

Im guessing that a sequential kit for the evo could work. Im probably wrong but I dont see how it wouldnt. I think Buscher makes a kit.

Ive often wondered if it is possible to swap the slap shift from the galant version of the 4g69 into the ralliart. I bet that would be interesting, especially for us auto guys.
