I don't think so. Even if the CNG stations open for twice a week, the lines would be huge like they used to be before this winter shutdown.
And in upcoming summer season, its extreme torture to stand in those queues for hours.
In Punjab, CNG does not have a future. The governement will cut off CNG supply from 2015 (Before winter). After that CNG industry will itself import LNG and then convert it into CNG. You can imagin the rates.
The best solution is petrol efficient cars. EFI engines consume less petrol than the carburettor ones.
