I'm sure that's fine, as long as you have them sitting up (as aruba5er stated). If they can support an entire building, I'm sure they can support your 5'r.
Ahhhh... they support an entire building because they are filled with concrete are a essentially "solid" concrete...not hollow blocks.
Putting four down with the holes pointed up and having a 4x4 stretched across them, should be more than adequate to handle the weight of your 5er. But as others said, that's a lot of extra weight to haul around. I think I would go with the plastic blocks myself.
