I beleive you need full paragon or renegade but im not sure, however you should easily be able to keep them alive, just buy all the ship upgrades, dont use them in the suicide mission (Samara for the barrier, Garrus or Jacob for squad leader amd Legion for the shaft.) and you should be fine, it may also help to leave very defensive characters like grunt and zaeed behind then you go for the last stage of the suicide mission.
