they are from the same family so they are related but that doesn't matter because only brothers or as close as brothers are compatible enough for the EMS another thing that would work is if a member of the senju wore the eyes first

the reason being is that the only reason uchiha go blind from over use is because they did not inherit the body of the sage. and as such they have a physical weakness so logic dictates that if a senju stole the eyes of a uchiha the eye would instantly be Eternal

The Senju thing is only speculation, bro. It would only really work in a person who is both Senju and Uchiha simultaneously. The Senju would have to awaken the Sharingan themselves, with the optic nerve chakra originating in their own brain, and have that chakra meld with their advanced Senju chakra, for this to even have a shot of working.
