Should I apply for a job I might not want that’s posted by my direct supervisor just to make an eligibility list?

I work for the federal government. There’s a system where you apply for a job and then get on a list of eligible applicants (called a cert list) for that and similar open jobs that other hiring managers can pick for for interviews. Many jobs aren’t posted directly but are selected from this list.

My supervisor posted a job announcement for a position that will become my supervisor (adding a new layer between myself and my current supervisor in a reorganization). I most likely wouldn’t want that job for various reasons. But it would be good to get on this list for similar jobs. It would be a higher grade (a promotion for me).

I’m just not sure if I should apply. It might be awkward if I made the cert list. If I were to be interviewed and offered the job (a big if) I think I would probably turn it down. Might that make it uncomfortable? Would it be uncomfortable if she didn’t select me for an interview? Or…maybe I could apply and have an open mind and worry about the if’s later?
