Trying to do high fantasy using the WHF rules... hmmm kinda hard as high fantasy is usually about having very fluid classes. Mage-Warriors, sneaky types with illusion magic, etc, etc. WHF tends to have people stick to their class, very medieval but sets the tone well. But I like the system!
I'm thinking of adapting the WH40k RP rules to a fantasy setting. More talents, more choices as you "level up", and in a way high tech is like magic anyway. Of course there'd be no bolters or whatever...
Since the two systems work fairly well together it could be done, the biggest over-haul would be magic, as it needs something to limit casting it.
