i don't hate this theory, but i have an option to it. what if the senju have a kekkei genkai that allows them to innately absorb natural energy? like Juugo's clan but at a far better rate. and, like kimimaro's clan, only a few in the clan can access this ability (hence y hashirama can and his brothers can't). if this absorption works, it'll grant him the ability to access sage mod with an animal path.

inversely, if hashi was a slug sage (which is plausible since summons tend to follow family lines), it would make sense y his markings look that way. they somewhat resemble katsuyu (not saying she's his summon. maybe its her parent or relative). with his power level, he wouldn't need to summon his slug and if it died before, it would leave a scar on him to not summon any more. this theory could be plausible if there was more context to go with it about his teenage years.

and in regard to rasenshuriken... what if the absorption of natural energy is what makes wood release stable... like how naruto needed it to help the rasenshuriken so he didn't get hurt
