I did Wish for dozens of years for that compatibility but unfortunately, I couldn’t get both. I always wanted to experience the ultimate gameplay and push limits out of this game and tried many mods around the vault. Long story short, the NWN1 is pretty complicated for this just to get straight what you want. I always wanted to have more than 1 henchman in the party, control henchmen, make henchmen mart and intelligent, watch AI bosses fight each other, recreate huge battles from DnD lore via the editor, enable AI on my own character and so on.
Regarding AI as smartness boost - Tony AI. The problem with it is that is heavily outdated and it was never fully finished, there are a lot of bugs, but from my experience, this is probably the best what you can get now. There is an upcoming new AI of Jasspere that I’m personally waiting for for years and only will install the game again after the new AI will be released because even Tony’s AI doesn’t provide a nice gaming experience, especially with different modules than OC/SOU/HOTU.
Regarding more henchmen in the party - by default, only OHS mod gives you that ability but takes away Tony AI. The closest you can get to get both mods I found only a partial workaround. It allows you to get more than 1 henchman but only if they are already made for modules. That means you can’t create a companion and make a custom party like in NWN2 but allow you to recruit companions if you can reach them, for example in OC you can hire all 6 companions in ACT1. However, they disappear at ACT2 but you can recruit them again at ACT2. Lilith game editor You can play around with this tool, there is a function somewhere in the menu to increase henchmen limit in-game. There is an option to duplicate any NPC or PC as a copy to be in your party or make as an enemy.
These are general bug fixes and improvements of the game as well as AI too.
These are fixes and improvements of the game in many aspects it also has OHS compatibility to some degree. Be aware it is old as the universe and compatibility as the whole are questionable…
Many various tools to play around one of them are Numos’ Minion Command Tool where you can directly control companions and they attack enemies on sight, so as a wiz/soc you can finally tell your barbarian or paladin to go first through the dangerous dungeon doors!!! And these tools are override.

Alternative command tool
All of these are not willing to work together… I made myself a lot of workarounds and took only some parts of the mods and configured by myself exactly how I want without unnecessary stuff that I don’t like so technically it is possible but takes a long time of testing and I no longer have a game installed. But feel free to ask anything maybe I could help you make things work.
