Hi, new player here. My buddy and I recently got into Epic and are putting together the first of what may be several armies...

I am working on finishing off my Squats. I picked up some Exodus Wars Khazari, and after augmenting with actual Epic Squats, are pretty squared away.
Question though: I have two Khazari Mining Machines on 40x40 bases. What could I use them as proxies for...?
They are missing the drill, so I thought about purchasing some bits from Onslaught Minis, and calling them Moles or even a Hellbore, until I purchase the exact model. I also considered plunking a large barrel on them and calling them Goliath Mega Guns... But how often would I use them in a list?
So if anyone has any ideas, I would love to hear them!
Cheers!
