So, it's already done!
You can download the zip folder from my Nexus site for StandStillWhenIAttack (just follow the link in my signature); it's under Miscellanous.
Unpack to the main directory of your game folder. The folder structure should - hopefully - be the same as the Steam version.
The changes to equipment, skills and stats of Bairdotr all apply well (tested).
The build looks as follows:
Attributes:
Int 8
Speed 7
Con 6
Abilities:
Geo 1
Pyro 1
DualWielding 2
Willpower 1 --> probably it's a good idea to invest in bodybuilding soon
Talents:
Stench
FaroutDude
WhatARush --> for mages, who use to be on low health quite often (due to less Con), quite useful (extra AP on low health for healing purposes)
Skills:
Summon Spider
Boulder Bash
Flare
new Equipment:
Earth Robe
Two Earth wands
Scroll of Fireball
I hope it applies to you!
For changes just edit the files as you like. It's very easy to do that.
Also offered to all other players who are interested in playing Bairdotr as a mage.

Edit: Please note: Only stats seem to apply for existing games (but before Bairdotr is recuited I think). Equipment and skills require a new game.
