Not likely to see the -115B on the -200 passenger aircraft. Unless Boeing can increase the fuel tankage there is no reason to increase the MTOW.

RE: SFC Vs Raw Fuel Burn

The short answer is yes. SFC (Specific Fuel Consumption) is the rate of fuel burned/a specific thrust value. It's a linear relationship between SFC and fuel burn. So if for a given thrust value SFC is reduced by 1%, fuel burn is also reduced by 1%.
