I keep saying Rip the Cyclops has to be worth something beyond mere canon fodder. I bet Doctor Pete could do some magic.




Regarding lung transplantation, well, it does not look good.
Rip or any other person need to have the same blood type (as we don't know Stan, we don't which he have and as such the world population with the same could be 0.5% to up to 42%) and he would also need to have a similar build to Stan.
Also HLA shall be similar (I have no fucking clue what that means in statistic).
But even if Stan gets Rip lungs (depending on that Rip's rip cage wasn't ripped open with a bullet or knife...), his chances of survival for the first year is only 85% and for the next 5 years only 60%.
