I'm thinking about tucking a flat tank under the bed. Similar to a passenger tank but shallower. I would make it as wide as possible but keep it thin enough to be hidden by the bed. Perhaps extending some into the space between the bed and the rear crossmember.
Maybe a 34 style tank could be modified somehow. Not that far on the assembly yet. I will need a seat riser to replace the stock tank but that's easy enough to do, even use the stock cushions. Nice storage area under there too. Filler neck would have to come out the side like a 34 or in the floor of the bed.
