Need help with proxy-ing

[ilovethenids]

So, I'm planning to hopefully play an 1850 point game of 40K against my dad (Necrons). Problem is that he doesn't have many models (only a bunch of Warriors and 4 Immortals). He wants to run a monolith, 2 overlords each with a 5 Necron Lord Royal Court, a unit of 6 Canoptek Wraiths, and most likely a few of the Necron vehicles such as Night Scythe, Command/Annihilation Barge, etc. I'm wondering what I could use to proxy any of the vehicles/the wraiths, because I don't have any models of similar size to use. I have to know before Tuesdays since that's when our game will be.

Thanks

Only one I know is the monolith that is like the size of a gallon of milk

Wraiths are about the size of zoanthropes. Not sure if you have any zoans he can use =X

Monolith is smaller than a gallon of milk, gallon is too wide. I'd say the actual dimensions are a BIT wider around than a half gallon of milk. But yeah, it's sizable.
