Try your setup, but I have a different opinion:
1. If you think of healthy and strong fish that’s good, but why then don’t you think of healthy and strong plants? RO water is not the adequate water for Vallisneria and Ceylon-crypts. They may survive but they are not adequate to a blackwater environment.
2. Certainly, being accompagnied by Boraras is in principle a good idea for Paros. But it’s always a matter of what you want to achieve. The “survival of the fittest” in such a tank will result in slowly all young being eaten. Mind, that in the case of the Paros you are dealing with fish that are doomed to extinction. In my view this means at the first hand trying to propagate them, not to buy enough wild-caught to arrange a nice community tank. But maybe this is a somewhat extrem opinion. If you think that to an end consequently you should add Luciocephalus and even Channa to your community. An aquarium always has a structure which omits several important features of a natural community.
3. No young Paro will feed for about four to six weeks on Grindal worms. You will need Rotatoriae at best, or Paramecium as second best, maybe you are lucky with the smallest Artemia naupliae, the California type. Most Artemia are too big in the beginning.
4. Paros in small breeding tanks are no “lazy captive fish”. They have been givven the chance to propagate; a chance which is very small in your set-up.
But do it like you want; I wish you success. You wanted to hear my opinion.
