At Aldhick's suggestion

:
Has anyone considered taking the Ancient/Medieval army lists and adding a fantasy element to them? Options could include:
1) Wizards, with spells chosen from the nearest geographical Warhammer world equivalent nation to the Ancient/Medieval one.
2) Ogres, 1/1000.
3) Giant, 1/1000.
4) 1 suitable monster mount per 1000 points, monster type perhaps chosen by dice roll.
5) Mercenaries/allies from a Warmaster fantasy army list.
6) Something else.
By adding a fantasy element to the historical lists, this would enable them to play against "standard" Warmaster Fantasy lists. It wouldn't be "fair" for a historical list to not have any monsters, flying units or magic, would it?
One problem might be that the historical lists seem to have different points values for unit types in comparison to fantasy ones.
So Empire, Orcs, Tomb Kings, Chaos, etc., playing against a Crusader, Imperial Roman, Mongol or Korean historical army list that has had fantasy element added to it for example.
One obvious difference is that all Fantasy cavalry is based as "Shock", whereas most Historical cavalry isn't. But that might just be a challenge for the Historical General?
Alternatively, the Fantasy army has it's fantasy element striped from it. So no monsters, flyers or magic!
Both might make for interesting battles? Comments/thoughts?
