It was simple and painless when I PC'ed from Citi Double Cash to their Rewards+ card...
How long ago was that?
Your scores look good for this environment. Your AAoA looks a little short. But you're going after a PC, not a new card.
If I were in your shoes, I'd do it. Of course though, I would be OK if they denied me. If you had a lot of spend with your Citi card, I think that would help.
