I've recently sent out an article for review. I've been in email contact with the editor from journal #1 from the start, and was quite up-front that I wasn't sure whether or not my article would be a good match for their journal (in methodology, yes; in century and author focus, not so much). Today, I found a special issues CFP in journal#2 where my article would be extremely relevant. Their deadline is end of January.
I'm considering contacting journal #1 to see if they've started the review process, explain that I've found what may be a much better match for my article, and ask about withdrawing my submission if the review process has not begun.
Is this frowned upon?
Of course, I feel like I'm playing with fire here. What if I withdraw, resubmit to journal #2, article does not get accepted, then... go back to journal #1 with tail between legs.
