I would definately drill the tank. It is not hard to do just do a bit of reasearch and go SLOW. I have drilled many tanks down to ten gallons. The thin glass is a bit trickier.
The sump has so many benifits. The water in the main tank is always right full, there is more water volume so the tank is more stable, there is place to store the eqipment(skimmer, heater, etc) so the tank looks cleaner. You can also turn part of the sump into a refugium. IMHO you will never regret drilling the tank.
You could also get a glass company to drill the tank for you if you are inclined.
Have fun!
