Generally, you have to break down the process to steps, building upon each other as you go along the way.
First, you have to achive a proper calibration to target densities (or target LAB values) on the selected substrates (an average, widely available low-OBA coated stock on your market for Fogra 39, and a similar uncoated paper for Fogra 47).
Next, you have to make sure that the whole sheet has the same calibration properties within a tight tolerance. Even in the corners you should have proper color calibration, not just in the middle of the sheet.
The first two steps might propel your system to a state when G7 or ISO 12647-8 is within easy reach, using the canned, factory-supplied color profiles. If that's not the case, you will have to build your own color profiles for each of the substrates, using a commercial profiling application and a lot of measurements.
When you have the press properly calibrated & profiled, you must be able to reproduce color with very high accuracy. To prove that to your boss (and most of all: to your customers), and to maintain this merry state, you should use an application like Bodoni PressSign (Print Buyer Edition), which can output a certification about the performance of your press system.
The first two steps is very system specific, I would start with an in-depth consultation with your local HP dealer / technician. They should know how to tweak the press to it's sweet spot.
