Can I make a map w/ AI & Vehics and play with friends in a private match?

I know it wont let you validate it for multiplayer but is this stopping me from playing it with my friends in a private match?

We were looking forward to creating a jurassic park map where you basically cross through dense jungle with tigers as velociraptors and see if you can make it across without dying.

Looking for a bonafide answer on this as this is something I'm looking forward to quite a bit and it'd probably change it from a day 1 buy to 'eh, i'll pick it up in a few months for 30 bucks'
