I suspect the tanks required to store the hydrogen will weigh significantly more than the current retaining walls for the fuel tanks on planes.

Hydrogen would need to be pressurized to be able to hold sufficient weight for a flight may be not to the extent it is for space travel.

I like your thinking that 20 years out we may have differently shaped planes because they run on HYSR produced hydrogen.
