Natural Gas instead of petrol

[Mark a Reed]

Hi all, 

Could a EFI system be converted easily to Natural Gas by connecting 
the fuel rail to a gas bottle with the appropriate pressure 
regulator?

If the regulation pressure was set correctly then the fuel/air 
mixture could be set to allow the use of existing mixture maps in the 
EFI system.

Is this feasible or a wild dream ?
