the two middle beds have the advantage of being able to harvest both sides of the beds and for ease of tying sweet pepper plants to canes to keep them tidy
I would have done it a bit differently I would have had only 2 paths!
Imagine this:- 2ft wide beds at the sides and a 5ft bed in the middle this gives you more growing space and you will still get to either side of the bed to tie up etc.
See the picture below that is a five foot wide bed full of sweet peppers see how you can get around it and the extra row of plants where you are suggesting to put a path.
Then for annual rotation you could put your plants like the second picture i.e climbing plants up the side of the bed and smaller plants between, alternatively put tall plants in the middle and small plants up the sides.
I have visions of you damaging plants as you push your way through what will be a veritable jungle if you do as you are suggesting.
I hope you don't consider my comments as 'interference' but I once did what you are suggesting (sadly I have no photos to show you) and lets just say " I had problems" not least ventilation. Glad to see that you have already considered that problem.
There is also the consideration of light particularly if you are growing tall plants e.g tomatoes what I found smaller plants e.g. peppers become leggy and because of limited air circulation they often succumbed to botrytis.
However at the end of the day the choice is yours so I wish you every success choose which way you go!....Tg
