Engaged Couple double oil portrait

This client had a grainy image he took with his cell phone of a proof on a computer screen. The couple attended a wedding and the photo was in the wedding set proofs on line. They did not buy the photos because they had just begun dating. Fast-forward two years and they are now engaged and realize this was their favorite picture ever. Could I possibly paint an oil of them from this perspective-skewed, faded pixelated image.

I still don't know how I did it. But they're happy.
