Tarp for Bearpaw Pyranet 2

I already have a MLD Duomid and I ordered a custom Bearpaw Pyranet 2 (54" height) that is solid silnylon on 3 sides with partial mesh front and inverted T door. I ordered it that way for winter applications and it works fine inside the Duomid but I'm looking for a "simple" tarp setup that could utilize the Pyranet as well. If you already have a Pyranet then you know it is rectangular shaped and requires a center pole.

Any suggestions?
