I know, I know, alot of your are thinking that im crazy.
i pretty much am.
But, there are some clues to him having a little senju in him.
1. Silver/White hair dark grey eyes. it may not seem like much, but it does match the Senju criteria -Minus Tsunade
2. Kakashi is a very balanced Shinobi, in the 3rd data book, no skill very beyond one point, making him an all around shinobi. The senju were known as "The clan of a thousand skills" showing they too were all around shinobi.
3. Kakashi suffers no ill effects for his MS, much like Danzo didnt when he integrated Hashirama's DNA into his body.
4. This one is more of a side note, The Uchiha hated Sakumo Hatake. this hatred grew after Kakashi gained the Sharingan, possibly because of Him having old ties to the Senju.
5. More speculation... Every living Uchiha has had some form of fight with Kakashi, Sasuke, Itachi, Tobi and even Obito had all had at least a stand off with Kakashi, hinting to the fact that the Senju and Uchiha are almost destined to fight.
I know im Grasping at straws, but is there anyone on this sight that could see Kishi NOT having something like this happen?
lets hear some feedback, does anyone think this could happen or even remotely hold Water?
i think some of your points are a little off
1. hashirama also didnt have grey eyes and white/silver hair, and i dont know any other senju examples of gray and silver features aside from tobirama
2. in the data book its true that he well rounded, but i think the sharingan helped him out a lot with this
3. Kakashi does feel the effect from MS, even after he trained and developed his kamui, after only using it twice in the same day he would be in a hospitol bed for weeks, he is just now showing that he can use it much better, even tho it doesnt seem he would have time to develop it since he has been on missions for almost all of shipudden. Also, throughout the whole series, kakashi fatigues very quickly when only using one sharingan at base state, uchiha feel almost nothing from using their base form, Danzo (who never used the MS btw) could handle ten sharingan with senju (hashirama) cells. Kakashi doesnt have the crazy endurance quality that the senju have
4. this might be true but its a long shot, it didnt really seem like anyone got along with kakshi except for guy, naruto, and sakura. Even when kakashi fights and uchiha, he gets scolded for having the eye but they also show respect because he uses it well, sometimes better than the uchiha.
5. Just cuz kakashi has fought every living uchiha including itachi, that doesnt mean it had anything to do with uchiha and senju conflict. kakshi was actually the one who showed up to the fight not them going after him.
Itachi v. Kakashi, fought to protect naruto, same for both meetings
sasuke v. kakashi, kakashi showed up to save naruto
Tobi v. kakashi, kakashi aagain showed up to help naruto, before that kakashi happened to be with naruto when tobi wanted to talk to naruto
even though ive proven most of the point wrong, i still think its possible. Maybe there are better clues to prove this, but its not that relevent to the current story, and they might never reveal if he is or not
