The second arm won`t do much for him except for some taijutsu feats, but he uses a sword regardless and he only wields it with one hand to begin with.Probably he can just conjure a susanoo hand regardless if he feels like it.

As the curse seal, you might as well give him his original curse seal and that would buff him plenty.

The second pair of rinnegan would be the most interesting. For what we have seen from Madara`s Limbo, i`am assuming that amenotejikara would be the most affected technique.Probably Sasuke could use it for a longer range (longer than his usual range of 70m or whatever it was) and i`m assuming that he could spam it much often without having to shut his rinnegan down and much closer in time intervals.And that would be dope.So that would be the biggest buff of them all (excluding the TSB you gave him but that`s out of order for him).

Oh, and the user doesn`t just randomly have Nagato`s feats from the Asura path like the robotic arms or the rockets or whatever just because he has the rinnegan.
