I went to Cal to see a two place Baby it was side by side seating and had an extra 2 foot in wing thru having sqared of wing tips but it did not have the right looks about it so i did not buy it it also had steel truss landing gear that also looked odd I think if you build a two seater then do it tandem it looks much better and I think a center section is needed to give a little extra wing area is a good idea but I am not an aero designer so i eould leave that to somebody who is My 2 cents worth Ed
