making cream with almond milk and fat
You should be able to mix almond butter into almond milk to raise the fat level to that of cream. That should be enough, assuming you want the cream as cream, or for a ganache or something. I've certainly done this with coconut milk and coconut oil, and used in a ganache for a chocolate cake.

For whipping, you'll need something with more stability than almonds. Adding gelatine or xanthan gum should help with that.
