I play similar rules in my path to glory:
Warbands start at 500
The leader has a special artifact called divine shard who give 3 extra wounds to evry unit( not to evry single model. The whole unit, like a mystical shield who cover 3 wounds). So the game last a little extra time.
The First winning game give an artifact choose to the player
In some battleplan i made special home rules to use common enemy with AI, their defeat give extra point . And other special focus give extra point.
We play in 2, 3 or 4
Its very funny and easy ,because only with a few models battle Can be boring if you are an expert player
