Sleeps four and looks like a teardrop?

Has anyone made the 2+2 or something like that from the design library? I've been using the search but not having luck. I've been interested in Teardrops for years, but now have two small kids that we can't put in a seperate tent. I love the Teardrop shape and was thinking of trying to do a 5x8 or 5x10 maybe 5' high and some how shoving a cross space for kids. I might have to resort to making more of a TTT. I've thought about having a front hatch that somehow folds up/down panels to make another space, but that goes against KISS. Any examples of that? I might have to go with TTT and wait until the kids are older or out of the house to get a teardrop.
