You want the rebar completely enclosed by concrete. There should be
four inches of concrete between any rebar and the outside.
They make little concrete blocks to support and stand off the rebar,
especially for this purpose, and the pour goes around them.
What you are suggesting is a no-no.
Wire the basic framework together and lower it onto the blocks and
then finish it if you want to.
