diaphram design w/o plywood
ask fiberglass panel manufacturer for info on diaphragm capacity and connections requirements to transfer load.
or provide horizontal x-bracing to create horizontal truss to transfer load to shear walls.
depending on the dimensions of the "small" restroom, you may be able to provide a beam built into the top of the wall that would span horizontally from corner to corner.  this beam could be designed to distribute the wind/seismic forces to the end walls.  of course the connection of these beams at the corners must be carefully considered.
perhaps horizontal straps across the roof, like those used in metal stud shear walls.

thanks for the reponses.  that gives me a couple options to consider.  thanks again!!
kramer's suggestion (beams to distribute shear aplied at the top of the wall) has worked for me in prefab restrooms where the roof isn't connected to the walls for insect screened venting purposes.
the biggest problem in this type of building is to make sure it is adequately anchored to resist overturning and sliding with sufficient safety factor.
