Yup, I see where you're going with the mods. It's amazing to me that they had so much 1" PVC on that booster and then just flared it out to 2" PVC like that. Do you have flow rate issues on that pressure port?

My inclination would be to do all the modification work at once but I know what you mean, good Jandy valves are expensive and putting in 4 at once would cost quite a bit of coin.

Good luck and don't forget to post your mods when you are done

Cheers.

PS- the aquanaut cleaner looks cool. I have not read any posts about it yet so is be interested in hearing how it works out for you.
