Well, using a Tasmanian Devil as the host doesn't create a new critter - all the genetic material still comes from the Thylacine. The host is just
an incubator; they'd use something easier like a sheep if they could, but since the T-Devil is more closely related, it's more likely to supply
proper nutrients, temperature, etc.
(The T-Devil is probably the marsupial Advisor was referring to.)
