We've actually done this before. Our process has evolved over time. We used to bring candidates in for a day to work with us and have them work on production code. We would pay them for their time.

Unfortunately, it wreaked havoc with the candidate's schedule, especially if they had another job, and took too long to get to a pass/fail for them.

The current process let's the candidate work on a production problem, but at a time of their choosing and on their own schedule. It also gets feedback to them much sooner, within a half hour or 3 hours.
