It wasn't an organ transplant or anything. Considering Theo was their only other success and they performed the transplant surgery themself, the dread doctors could have done it. That goes for all the other options too i guess.

As for Danny being a minor character, he was a recurring character for 3 seasons. That's the most for any teenage human.

The only other humans who are a tiny bit more than minor are Sydney and Jared. This is assuming that supernatural creatures cannot be used.

However if supernatural creatures can become chimeras then Ethan and Brett are also viable options. Ethan would make more sense since they could use Aiden's organs for a transplant like they did with Theo and his sister. That obviously depends on when they started this whole thing.

Overall, Danny seems like the most suitable option. (IMO)
