Chest-wise, you sound similar to where I was pre-op. Not sure on skin quality and all that, but my surgeon and I had a pretty frank discussion about all of my options, since she has done all of them.
She said she would do a peri, but she was positive that I would need at least one revision to be happy, and she could see doing as many as 2 revisions on top of the original procedure.
A viable option we discussed was doing peri with a lateral extension incision into the armpit area to remove excess skin and tissue. I've only found one of these online, and it was hers. So not sure if it's something she does on the fly or if it's just not as well known of a technique. Again, she said she would do it but would likely need to do one revision.
Ultimately I asked her what she wanted to do and would feel most confident about. She said she was positive she could get it right in one go with a DI. That is what I ended up going with, and I'm 100% happy with the results. Sure, I have very noticeable scarring. But the procedure was quick, my heal time was next to nothing, and I don't have to go back in the future.
I would say take a consult with a surgeon that does both procedures and see what they say. Even if you don't book with them, it's good to have a professional's opinion.
