Then I am mistaken. I thought that based on the smallest tire that harris sells which is 34c, but my point is the same, even 30c is still a very wide tire and if she wants to be able to also use the bike for fast road riding, she will want to be able to use tires in the 23-25c width range. But, her idea of building it to accomdoate both 650b and 650c wheels is an excellent solution.
