IIRC, the Pegaso wheel are the same as the Funduro wheels, aren't they?
In this case, the front wheel will be usable (you can generally use the Funduro wheelset on the GS, but you need to modify the sprocket carrier on the rear, will the front wheel whould be a bolt on solution) without any hassle.
Again, Touratech springs to mind. They used Funduro Hubs for their Dakar bikes and on rare occasions even for customer bikes.
