"Teacher" Mod

Hello Baldur's Gate Community. I'd like to design and create a mod that adds "teachers" to Baldurs Gate 1/BGEE.

I imagine a fighter, after completing the Nashkel mines and entering Chapter 3, goes back to Beregost and besides getting ambushed by Elminster and a little girl also can meet an expert dwarven Fighter. This NPC can teach the player, assuming he meets the prerequisites, to be a berserker, kensai or wizard slayer. This apprentice training will come with a price (say $5k gold) and perhaps a quest or two then Ron the generic fighter will be awarded the appropriate kit.

Imagine Daniel, the monk, could learn the ways of the Sun Soul monk by apprenticing with a wise old man and learning how to wax on and wax off on the vases in the Jovial Juggler then could get back at all the kids that bullied him.

You see where I'm going with this?

I envision a mod where Kits being earned is a feature in BG1. BG2 has strongholds as class specific feature. BG1 could have quests and trainers that allow kits.

In this way, perhaps even it would be possible to "dual into a kit". Say a kitless druid duals into a fighter and could meet the expert dwarven fighter master and could possible gain a fighter kit. If the druid had a kit before dualing then I would not like to allow him to gain a second kit.

Ideally for someone to take use of this mod, I'd like them to start kitless as a generic class.

Challenge: I don't know Weidu, however, I am a general programmer and can look at code and kind of tell what it means usually. I am serious about doing this and willing to put in the work to get it done.

So just throwing this out there and soliciting help and seeing what you all think.
