Warhammer Armies - what if there were more hybrid races ?

In the early days of WHFB I can recall a unit of half orcs based I guess on the shady character in Lord of the Rings who resided in Bree.

I was wondering whatever happened to them. I think you used to be able to field half orcs in the goblinoid army.

Anyway, it got my brain juices going and I was pondering over which races might 'breed' and how their offspring might perform on the battlefield.

If, in the unlikely event a elf bred with a dwarf (what a concept heh ?!) would you get the ultimate battlefield warrior ? Good weapon skill for sure and probably an improved initiative but would leadership be 8 or 9 and how about toughness (3 or 4) ?

I thought it might be good for an amusing chat :)

let me know your ideas.
