Of course it is! You just need to do some major changes to the code if you want to have an instant FE reading. If you just need an average it's fairy simple because all you need to do is counting pulses from both flow meters and do some match to have it displayed as l/100km, mpg, km/l etc.
If you want to have instant reading you have count time between pulses on both flow meters.
