To evaluate this idea further, I'd want to know how fast (how much faster) the loan will be paid off given various salary percentages. Is this a good way to pay off a loan? (Do I even want to pay off the loan faster?) As an employer, you have to convince me to offer it as a benefit, which means convincing me that my employees will love it, that it will help to attract and retain great people. This makes me worried because it is one of those "vitamin, not painkiller" problems - and it's a niche one at that - I am worried that people don't want it and it will be hard to get into people's hands.
