You could go that route, but I would want casters mounted to plates that would bolt to the bottom of the wood.
Car Skates are the 1st gen curved metal plates with 4 casters on each corner that you can place under the cars tires so you can move a non-operating car around. Makes for a much more efficient use of garage space.
The Car Skates were very useful before I stripped the car down to the body and afterwards before I got it running. The Skates have holes in them on the end that allowed me to attach them to the 4x6's. I see the place I attached has metal frame supports for their skates and single wheel frame suppors that bolt onto frames (or wood supports).
