Civ2ToT Modder
Question, though, Karadoc. +2 XP for melee units would certainly be an improvement, but would it make the Dun worth building? To me, half of the reason why the Dun's awful is because it's on a building no one wants to get anyway. So unless you're planning some changes in the next version of K-Mod to make Walls more viable, I'm not sure if it'd be too much of an improvement.
What if it replaced the Barracks, instead? So it swapped out the city defense bonuses for the +2 XP you're suggesting, while still keeping the free Guerilla promotion. You could possibly even have it confer a free City Raider I promotion on Melee units (and with Boudica, free Combat I, Guerilla I and CR I makes the Gallic Warriors suddenly more attractive), though that might be excessive. You could also have it retain the 2x building speed with Stone, as a nice if perhaps mostly trivial boost.
I think that would retain and even expand on the Celts' "barbarian" flavour while making them a bit more competitive.
A dun can't be more of a barracks. A wall is for defensive purpose and guerilla promotion as well.

It's fits the promotion very well where Celts love to found cities on hills.
