Nope, no kit.
I have actually thought about scratch/converting one. You would need to use the Trumpeter M1084 FMTV and a launch pod from a Dragon MLRS (maybe Trumpeter in the future). You would have to scratch the rear rocket pod holder/launcher rack mechanism.
Another option would be to get the 1/32 Forces of Valor die-cast toy version and use its launcher rack as a base, with lots of corrections.
Maybe....
