anybody ever made gull wing doors on a TD?

I was thinking how nice it would be to have the door(s) act as a roof when getting in and out in the rain (it was pouring buckets and I was dreading having to get out into it). From what I figure it would have to be hinged up on top of the roof to have enough height to stand under when open. now I am trying to figure a good way to support it when open(ing).
Planning on an outside privacy curtain, think of a shower ring attached to the side of the TD, that snaps on to a folding bar on each side for each door, gull wing doors would make a nice roof....the shower ring would attach at the top fwd and aft of the door and when stowed would be below the bottom of the door (like a big "U"), the curtain would be those shower curtains like the hotels have that don't use shower curtain rings, just plastic split rongs molded into the fabric.
