Has anyone considering working on an interop mod that would make take the best of these balance mods and combine them?

I'd love to see a compatibility patch, but everyone on Project Nevada is either busy with SkyUI or there own projects at the moment.

At the very least, I'd like to see a light version or equivelent mods that has the perk and perk related changes (like to Cowboy or Grunt, Them's Good Eats, etc)

As far as I know they're mostly compatible. At least the core module and cyber module, PN's rebalance module won't be. Though I guess there may be some perk conflicts with the core module and JSawyer's mod? I know PN modifies some perks for its bullet time and sprint function.

I use Jsawyers mod with PN Core and Equipment and it works just fine.

I know Cirosan, author of the very good Cirosan Classic Overhaul, is working on a patch for compatibility with jsawyer.esp. I believe CCO is built with Project Nevada rebalance in mind, for what that is worth.
