Absolutely - I'd love to see both versions! Although there are a LOT of differences (in addition to engines) between a stock Cyclone and the A/FX drag versions.
Other than the body shell, glass, and maybe the interior tub, I wouldn't expect there to be much which could be shared, but an all new, accurate SOHC 427 would be really nice to have.
Lots of interest in vitage drag subjects right now. Wouldn't surprise me in the least if Moebius already had something like that in the pipeline, in conjunction with the Model King, perhaps.
I was just thinking wishfully above, and honestly don't expect such a thing from Moebius. I think they've done a good job maximizing the kit tooling they've chosen to produce, while not spending a ton of extra money on second and third variants, instead keeping them relatively close to the original issue. I doubt a '65 Comet AF/X would be a huge seller anyway, but I wouldn't complain if such a kit appeared on hobby shop shelves.
