Approx. 12 hr round trip with about an hour turn time, for a total of 13 hour duty day with only two legs. Then home and in your own bed to sleep. It can't be any more unsafe than the regional pilots doing 5-6 legs per day, and 14-15 hour duty days for an 8 hour reduced rest overnight at a hotel.

Best part is you only have to do 8 days of work for 96 hours of pay. I doubt it will hurt that much.
