It is possible (as long as you drill drainage holes in the bottom)
Bear in mind that the restricted rootzone differs greatly from the surrounding grass and in the summer, as the water evaporates more quickly and the soil warms up, a brown rectangle will be visible.
If you are able to get something made up that is deeper to stabilise the root conditions I think you might fair better but I fear never perfect.
Hope that helps

Almost finished on a new build with the same problem. I have lowered the covers and put down offcuts of "Lazy Grass" from an earlier project. Once down you can sow seed into this to improve the appearance. It's not perfect but it's better than the drain covers and as long as the rest of the garden looks good you tend not to look to closely at the lawn. The main advantagesare that it's easily lifted when needed and wont dry out and die in hot weather
Go to www.chambermate.co.uk - they cost me about £30 each.
Although there are no drainage holes in the product, this has not proved a problem, with grass growth being fairly vigorous and no summer watering found necessary.
