This is a great idea (assuming that the budget exist), because it takes care of retention, not just recruiting.
I'd split the bonus between the two employees, and have it stop if either leave the company. This way both employees (who might have some influence on one another) have an incentive to keep each other happy at that company. This can boost the retention effect of this strategy.
