I have two observations to make:
First, if you can't find a 103, you aren't likely to find a 106 or a 107, so go figure.
Second, as a person who hasn't really worked with a single football coach who sees enough benefit in wrestling to encourage his heavier players to participate, I am against anything that adds a heavier weight class at the expense of a lighter one. And I am at one of the larger schools in the state.
Going back to 12 weight classes might be the answer.
