Question :
Is there any sense to add styrofoam, I would rather use the
underfloor space for storage.

Then you are out of luck.

What you could do, is use the mixable type of foam and put a little
here and a little there - any spare space you have, put foam there.

Personally, I think it's a bad idea not to have foam in the hull.
However, it's your decision.
