Not this one. The Sculpted SA was one of the few "non-negotiable" aspects of this set, and that is a SP exclusive.
I realize there are quite a few right now, though the community does also love their SA keycaps. That being said this whole kit is based off a 50's typewriter and those higher profile keys really enhance the look and feel, which in turn enhances this set. Also, this is so far along that changing a profile now would delay the project for a very long time. Massdrop is on board, talks with SP are happening, so...basically not possible. Their pricing is great, totally agree, but my whole vision for this set would be compromised if I switched now.
Now, I've seen other sets where people were making SA profile sets based off of games, which was a little confusing to me. That is one of the cases where I would definitely look into/use a different profile. SA is pretty much just for typing.
In the future would I be interested in doing something through JTK? Absolutely. Could this set even be run as a JTK set one day? Perhaps, I wouldn't be against it if there was interest in the future. I don't create these these sets and want to "control" them, I really just do it for the community. I hope that was an acceptable and understandable answer.
