You are correct. The reason for omni-wheels is because you want less friction. When making an omni-directional drive, except maybe swerve/crab drive, friction is the enemy. It would work with the kit wheels but I can't imagine it would work as well.
I don't really think the omni-wheels are necessary, just strongly suggested.
