stage 1 and 2 rinnegan could stay as is, except stage 1 having access to all element trees, instead give a skill to create chakra rods(weapon). stage 3 rinnegan would be nice, seeing as its hard enough to use the paths already, if the main body also could rotate between the different path abilities it would be better. but then again, the paths are already very rarely used, so if they had the ability to enter/leave different maps, i could see them being used more. 
When it comes to the paths itself, the Tendo and Shurado paths looks good and i love the idea, but Ningendos kyuukon no jutsu, instead of making the target take 25% more damage, i think making it steal 10% of the targets hp and giving it to the path/user would be more useful. and the passive. instead of being able to get info on the kill, the path gets the ability to get info on whoever is standing next to him, aka in contact with the path, and then make the passive a 1% insta kill on punch if the target has less then 25% hp.  The Chikushodo skills looks amazing and would be wonderful if they were made possible, but instead of just being able to summon the paths, i say it should be able to summon a player from the same village/org as well. And when the summoning jutsu is used to summon a player a prompt will be sent to the player saying "... is trying to summon you" then they get to pick yes or no. The Gakido can stay as it is, but get a little tweak, where a prosentage of the chakra absorbed is transfered to the user.  As for jigokudos Meifu no Ou skill, if it were spit into 2 jutsus, 1 that takes life and another that gives life it would be cool. the first jutsu Jigoku kusari (Hell chains) which pulls at the very essence of the targets life slowly draining the hp till the target dies or breaks free, much like a bind, but with hp absorb. both the target and caster will be frozen during the jutsu. the 2nd jutsu Jigoku Tensei (hell incarnation) compleatly heals the targets hp, but the caster loses same ammount of chakra as hp healed.
