I don't know of a mod which answers your question, but have you considered alternative approaches to tackling the problem? A combination of AV Uncapper (to give diminishing returns on stacked enchantments) and bumping up the difficulty slider a bit would probably have similar effects in terms of game balance.
Hmmm, I have AV Uncapper because of SDR. The difficulty slider I am unsure about as to what it changes to make the game more difficult (more HP to NPCs, higher AV to NPCs, damage multipliers to NPC). I use Phitts Phiting Fixes to multuply damage x2 already, so NPCs, expecially archers, are able to kill me with 4 or so hits (2 in some cases).
Must be some way to cap enchantment making without an overhaul. I think Supreme Magika had something but LAME is mor emy liking by itself.
Maybe someone else knows of something?
