We have some guys here who are great with tractor hydraulics. MadReferee is one guy I rely on. But I can tell you that some of us with tractors can probably get you through the basics. I have a Top-n-Tilt system on the rear of one of my tractors and it allows me to use a "joystick" to adjust the rear implement 4 different ways. In my case its set up for front-to-rear tilt, plus side to side tilt, in addition to up & down on by using a second lever to control the hitch. So it is a 6 way adjustment, 4 way with one joystick, the additional 2 ways with a secondary lever.
For a front implement I would think similar functionality would be needed. Up & Down. Side to Side tilt. And then instead of front to back tilt like I have, I would think you rather have a side to side swivel to angle the blade. All of that could be done with 3 hydraulic cylinders, and either 2 or 3 levers. It would not take much hydraulic flow to power it either, probably just 1/4" lines is all you'd need.
