Those are cool ideas, but you can't just have ideas because they're cool.
And red drakes wouldn't fit - they only fit with the normal orcs when they imprisoned Alexstrasza in the Second War.
You need to have an idea of how the Fel Orcs are going to be played.
Do they mass? Do they make a few, very powerful units? Is offense their only defense?
I think that their units should be around medium strength, but have them be all about offense. They should be able to create quick forward bases, but slow economy bases.
That's just my take on it though - you can do it any way you please.
