I agree with sir82's assessment. If an acceptable alternative such as this manufactured blood were to be introduced, it would be a dream come true for the WTS and in my opinion allow them to never drop the blood ban, recommend this use in all cases (regardless of the increased cost) and avoid major lawsuits. I was shocked when they allowed Hemopure since it is made with cow's blood. Personally, I'd rather have human blood than cow's blood.
They could easily use the whole transplant reasoning and correctly compare this to having a bone marrow transplant, which is a personal choice.
