Agree with Cthulhu D that an advantage of short ♣ with transfer responses is that accepting the transfer can be a dustbin rebid, releasing a 1N rebid to show 17-19.
If you play Kokish, you might also consider adjusting notrump ranges.

• 2N = 22-23
• 2♣ - 2♦ - 2N = 24+
• 2♣ - 2♦ - 2♥ - 2♠ - 2N = 20-21

This means that with poor responding hands, you can sometimes stop in a making 3-level contract by breaking the Kokish puppet i.e.
After 2♣ - 2♦ - 2♥ -

• 2♠ = Normal puppet
• 2N = UNT Weak 5+ 5+ m e.g. ♠ x ♥ x x ♦ J x x x x ♣ x x x x x
• 3any = NAT Weak 6+ suit e.g. ♠ x ♥ x x ♦ J x x x x x x ♣ x x x

I think a really big question you want to resolve if you're going to play transfer responses is if you want the accept to be exactly three card support or a weak NT. This decision ripples through your entire design.

However, I like the moving the 20-21 hands into 2C and having the stronger hands in 2NT. I'm not sure I'm going to do it, but I see the advantage. how often do you get pre-empted?
