I'm also hoping people realize that "chopping off your legs and replacing them with robot legs" to combat g-forces pushing your blood out of your head doesn't fix the problem as the blood will still leave your head and go to your stumpy legs and torso.

Are you a doctor, like, medical human people doctor?
The human blood circulation system - I don't know how English people call it, probably Joey - is subdivided in two parts. One part serves the head, the other part serves the whole torso, arms and legs. Obviously they aren't completely seperated and the same blood stream flows through both, but it does have some effect on how efficiently your heart can pump blood into whereever.
Aside of that, the lack of legs reduces the travel length of the blood stream. When your blood is pushed out of your head into your legs, there's more blood mass to move over a longer distance than when you don't have legs. No legs makes it easier to pump the blood back up into your head: Less blood to move over a shorter distance. Remember physics: E = m * g * h, energy is mass times gravity factor times height. Less height, less energy needed. Furthermore, E = m * v, energy is mass times velociraptor.
I'm not a doctor, neither medical human people doctor nor doctor of computer science since I stopped after my bachelor's degree. My current profession is to make up things and post them on the internet. Have a nice day (:
PS: Yes I should've drawn some illustrations to support my made-up thesis of how removing your legs does indeed allow for time travel.
I'm personally not, but a friend of mine is currently doing his resident work, and we yap about hypotheticals like this a lot.
You're correct, it would lessen the impact, however, remember, the issue with a blackout is that enough blood leaves your brain that consciousness is lost(a redout being where all the blood rushes to your head, which is also an event in high-g maneuvers that chopping your legs off won't fix.
So it's not that "all your blood runs to your legs", but "enough blood runs to your legs so that not enough blood is in your brain to keep higher functions running". Chopping off ones legs would indeed give comparatively less area for the blood to flow, but I would point out that modern flight suits not only have the pressure bladders(used to combat blood moving where it shouldn't) on the calves - which is the region amputated in the theory - but also the thighs and lower torso.
So removing only a third of the problematic cavity that blood could flow wouldn't be anywhere enough to properly mitigate loss of blood to the brain(or, again, too much). It may well be enough to raise the g-force threshold before it begins to happen, but it wouldn't be a substantial difference, I don't think.
