Technically, If no other considerations matter (discussed earlier) other than fluid transfer, then Yes possible, and proven several times over the years (century!) in semi-controlled conditions still ended up with mixed outcomes for the donor and recipient!I think we’re straying away from the conditions TeeDee initially set, which is a hypothetical Hollywood style scenario where you really HAD to do it as there’s no other option.
It’s about the ‘technically possible’ rather than the ‘actually going to happen’.
So while _technically_possible in a hypothetical way, it is in no means actually doable in the real world imo.
