Anesthesiology to Allergy?

Current M3, considering anesthesia. I have a hunch I know the answer to this question, but just thought I'd confirm: Is it possible to have a practice geared towards Allergy/Pulm medicine after completing a CCM fellowship post-residency? I realize this is largely in the realm of IM, but was wondering if anyone has anecdotal examples.
