It would take time and a collection of community level-heads to properly lay out a system. I think
anything can be implemented with proper guidelines and planning just as Edo Tensei is. The thing is it's time consuming but not impossible. I personally cannot sit down right now and figure out a a balanced way of implementing these techniques. As for me I'm still catching up with the anime. I'm pre-final battle/ Obito becomes jinchuriki so my knowledge of the techniques are nil besides what I might see on the wikia and sometimes that's as legit as those degrees you can get online from the chinese.
As a community though our greatest issue- in my opinion is balance. I'm a huge fan of canon but fact is alot of characters just take it too far with the power-ups in my honest opinion. Notice my repetition of
opinion? I'm totally pro-character freedom but if you have nine power-ups a combination of doujutsu + other various buffs and KG it'll take a genius ( let's be honest there aren't a whole lot of) or someone with an equal or greater power level.
Sometimes I read a zone fight then I look at the character biographies of the ninjas fighting and there's no cohesion. There's very little in their bio of how said techniques were acquired nor any mention of training, their ninja rank doesn't reflect the rank of the jutsu they're using, somehow they've gained affinity in elements not common in their region/village and at their character's rank and age they have some unexplained prodigious talent so they've mastered the jutsu and or jutsus entirely.
My point is this is both a very fun and difficult community to deal with in term of roleplay guidelines but nothing is impossible.
