Nice one! From the rules it would seem like the RSA sticks around until phase 12 and can be bought (there are no rules explicitly preventing it from being bought that I can find, it just usually can't be purchased because it goes away before purchasing privates is allowed).
According to this post in the thread Allowed to buy in the R.S.A. private?, Frederico Vellani said that the RSA is just like the B&O private in 1830, so the RSA can never be bought in.
