Erol, Ron, Nemo and agadoijo,
Thanks for the responses and great inspirations with yours and other's builds. Lot's of good ideas to work off of. I love how Nemo's has the curved part going from the sides/doors into the glass, but you definitely lose a stud by doing that I was thinking about using part 11477 curved, slope 2x1 no studs and mount it vertically to give a hint of curve, but save a little bit of space. One cheat I considered is using 99780 1x2 Inverted Bracket for the hip joint to better represent the size and scale of a seated MF. Aside from possibly offending purests, the disadvantage of that is a lack of lean which can also help fit the figure in.
Hopefully, I'll have a finished product to show you all.
Thanks again
