It'd be pretty hard to design such a CS anyway. The CS of Hyuga is their custom technique they would never give away, and while I do think that more ordinary CS can be created, I believe that any ordinary CS isn't going to work on an Uchiha for extended periods of time. As far as I remember, Sasuke could easily broke Danzo's CS placed on him through release of a powerful chakra, and all the Uchiha were noted to wield a powerful chakra. Also, this method seems even more discriminating than the actual one Tobirama used. Nothing would guarantee the success if such markings are about to be placed, since Uchiha can detect the Anbu, and then they wouldn't be standing still and waiting, resulting in an actual revolt and a civil war all the higher-ups tried to avoid.
