Using PMDG's FMS in Hawker

I know this might be a bit of a headache to do, but if I purchased the PMDG 757 or 777, could I use the associated files for the FMS and displays to make the corresponding gauges in the Hawker work? I've been looking into the files associated with the panels and as long as the panel files for the PMDG aircraft use a similar layout, I would think you could rewrite some of the Hawker's panel language to access the increased functionality that these payware products offered. Just a thought... if you think it too big a PAI (that's not Project AI!) tell me :)Zane
