I quite honestly enjoy the idea of the proposed F1 changes, but honestly I would not mind the lack of an overhead at all if instead his grapple was given more hit advantage for better Oki. Granted I am unaware as to whether this would imbalance him, but I thought it would be a nice consideration so that he becomes a better grappler. Another idea I have been contemplating is whether a speed up on F2 would be a better universal change than a speed up on F3. This would indirectly buff Outlaw due to his well-known +1 F22. A third idea that I was considering is if instead of ex-sand in Outlaw being simply safe, it could become similar to his prepatch sand grenade, causing the variation to undeniably be his best for pressure. Gunslinger is quite honestly still decent, and having played Marksman for the better part of a year, I'm quite confident that he is viable. He no longer fears armor when canceling into upswing (exceptions obviously being the strings that can be normaled through) and he still hits the same damage barring some midscreen jabs. His only major nerf was truly converting after run in punishes, but that's honestly it. It was very rare for me to ever cancel more than once in a single confrontation, but then again I've honestly never fought many great players. I'm mostly just theorycrafting here tbh.
Side Note: What would be a good buff to Marksman? I don't play him to often now, but I did notice that when I did I found myself winning through 21122, rarely using F13 unless I had some major frame advantage.
