I've done an oversized king - about 104" x ? FMQ and SID on my Bernina on a small fold out table, with the excess quilt draped on top of the guest bed behind me, on a tv tray to the side, over a couple of stacked up boxes to the rear, it was quite a set up but it got the job done! Just couldn't answer the phone once I got in there. I posted a pic called Oak Leaves somewhere on here. Good Luck, have fun, it can be done!
