Feral Orks

Hey I just found a PDF for a feral ork army and I was wondering if I could use it to bolster my Dark Eldar during big games. So my Goblins & Night goblins would become Gretchin mobs, my chariot would be a Junkatrukk and so on. would you guys mind that? If it would help I have a dark lance left over from my raider that I could glue to my chariot. Oh and I also have a looted sentinel but that's something else enterly.

Uh, big games don't have to have many units. You can just have allies. For big games, but team up with people and put your existing army in.

As your collectiong grows, you can contribute more units. And just have biiger 1 vs 1 games.
