14 ga is a tight fit, on most driveways. Seen people doing this method for years. Been called in to trouble shoot many of them shortly or a couple years later. The only way I would suggest doing this, is to cut the very shallow stress cut a little wider and at least an inch deep.
I prefer my lighting installs to be professional grade, so just spend a $100 or so on an extra GFI on the side of the house where all the lights are going to be anyway. Shoving wire in the driveway is a hack in my opinion. An average lighting job (professional) should start around $1000 anyway, so a $100 or 2 extra for another very handy GFI for the customer is just smart engineering.
