DaCypher-I do back squats about once a month for a little variety and to see how well the strength I gain from front squats carries over.I've never really got good results from back squats so I don't really emphasize them.
My leg workouts usually begin with overhead squats, working up to a max 3 or single.These really prepare my quads for front squats which is my next(and core) exercise.
I think you're idea will work well.After your regular squats, do 2 or 3 sets of front squats, focusing on form not weight.Once you have progressed a bit, alternate regular squats with front squats at each workout.One suggestion for you.You might want to do low reps(1-5) on the front squats.Holding the bar in proper position across the front delts can become a real bitch so the fewer reps you use, the better.Once you start to become fatigued, the bar starts to slip out of position.I'm working with 255 right now and by rep number two, I'm fighting to keep my elbows up.Good luck to you.
