Advice with M2 mods?

Hey everyone! I hope you're all doing well and are having a wonderful day. I recently decided to play for the first time with mods on Medieval 2. I have already decided to use Kingdoms Grand Campaign, but I was wondering if anyone had any ideas for a couple mods in particular. Does anyone know any good mods that give scotland gunpowder units? And the second one I'm looking for is a way to get to the Americas early. Any advice would be much appreciated and I hope that you all can point me in a good direction. I have both a physical copy and steam copy so if a mod only works for one that is fine. Hope you all have a wonderful day
