My weak intuition is that pro-life people would support anesthesia. For one reason, they may support it precisely because of the reason you give that pro-choice people do not support it (that is, the implications of moral personhood some people may infer). On the other hand, one counterexample to my intuition is the analogy to how some animal rights activists oppose welfare reforms or at least discuss them with a negative tone, due to a more absolutist or anti-incrementalist position.
But perhaps more importantly, if it's true that pro-life people generally would support it, I would expect that to make it less tractable, because there's a risk pro-choice people would react and be polarised against it if it was seen as a pro-life political weapon.
