*Opinion*. They're not super, super big and I think 5 gallons is more then enough to finish them up, especially if they're going into their flowering stretch.
If you do want to pot up, I wholly believe that there would be a very slim chance of transplant shock. They're still moving in full gear for another 2 weeks or so. If you're gonna pot up, I'd definitely do it now before the stretch and growth ends. Also! Maybe start with one to a 7 gallon pot and see how she does. No issue? Move the other👌👍.
No matter what you choose to do wolf I wish you luck😀
