I would most likely go in the side of the downtube coming out on the upper side of the bottom bracket and then in the bottom of the seat tube. My HT has routing in it for stealth and would likely do similar.
This could get interesting. Are you pushing your frames limits? If not, indulge yourself.
Enduro has limits quite beyond my capabilities and even more than the terrain here can allow. Is pretty massively overbuilt in my opinion. Built to take all the abuse that can be dished out to it. I've had some high speed offs and intos, frame has never missed a beat. Few scratches is all
My only comment is being alloy it should give you warning before failure.
Catch is...those stress areas and junctions are also close to where you would probably be putting the cuts. Heat treating, weld stress, force distribution, tube butting, internal gussets...I'm not familiar enough with your specific frame, what shape are the tubes? There is a lot of maybes in it. However someone in a factory somewhere does something fairly similar already, there must he a magic process.
Unfortunately there is no like button on here, but two thumbs up....
Just make sure you can pass a cable between the bb and the seat tube entry before you drill.

You've got this all wrong. Drink beer and drill! Film for scientific research.
