Perfect is the enemy of good enough.

Whatever combination of tension, spoke prep, or other magic was applied to your wheel when it was built is going to be disrupted if you proceed to make it perfect. If you're going to go tubeless, get the next size smaller tire.

And if you decide to mess it up anyway, I'd just tighten the NDS spokes a quarter turn. IIRC the NDS/DS tensioning ratio is about 3X, meaning you have to turn NDS spokes roughly 3/4 turn for every 1/4 turn in the opposite direction on the DS spokes. To retain the same tension you've got now you'd want to detension the DS spokes about 1/12 turn -- hardly worth it.

Just remember the best advice is often "Don't just do something, stand there!"
