Oh no, here comes some major trial and error and useless costs.
O.k., anyone with any ideas?
I'm thinking a wide base of say 23" so as to allow for angled 2" x 4"s or 2" x 8"s as bracing.
Put wheels at six points(corners and midway)
Then just copy a tried and true framed screen(if you guys know any links

)
I have 23" of clearance width-wise to wheel into extra room when not in use.
I have 80.25" of clearance height-wise.
I have 118" of clearance length-wise.
I was thinking of using either two pieces of 4' x 8' laminate and sealing the seam as best I can -or- doing that but then adding wallpaper liner over top before painting.
*If I kept the screen along a wall in the same living room I would have basically unlimited size concerning length and height...but same 23" as max for width of base.
