There has been some work done on a high-profile SHIFT in the past, which unfortunately was not able to come to fruition. I've always pushed for this to happen personally, and will absolutely pass along the feedback and interest. That said, it is not currently in the near-term plans to produce a high-profile version of the SHIFT.
HoffmanMysterYou definitely should, I'm surprised it hasn't happened. It almost seems like a missing piece with the ALT and CTRL having high-profile versions. I would definitely buy a high-profile SHIFT if it had the same design language as the CTRL and ALT high profile. (Or even better forgo the exploded arrow key design so the main layout looks more modern like a WindX98 keyboard, Wind X R2, or the best looking keyboard available right now IMHO - Mode Sonnet - but that may be asking too much!)
I can't guarantee they just work cause I had to stab mine and force it at the numpad enter key but I was able to make Everglide V2 Screw In stabilizers work with my Shift V2.
