Battle Isle 3 Mod

I'm willing to pay a BTC bounty to whomever manages to edit/alter the experience points system in Battle Isle 3.

(Yes I know there is Advanced Strategic Commands but I don't like it at all.)

There are quite a few mod tools for Battle Isle 3 but none is able to change the effects of bonus experience.

A few solutions I'm looking for:

1) no unit ever gains experience (worst solution which I would still prefer over the standard game)

2) limiting the experience to a lower maximum value, cuz maximum xp is OP (slightly better solution)

3) a tool which lets me set/alter/edit many or even all the values which are linked to the experience points system (best solution, like a mod tool)

Why would I want to change the xp settings in Battle Isle 3?
Simply put, the game is way too easy and the main issue is the totally akward bonus stats
a unit gets with higher xp.

Depending on the provided solution we can talk about the btc bounty.
1 or 2 should be doable by a hexeditor ?!
