From what I know (mostly quoting fromTrubshaw's book), things would have been even better than that.
Reheat on the existing aircraft supplied about 25% extra "wet" thrust.
The Olympus 593 "B" engine was going to have about 25% more "dry" thrust, so the reheat could most likely have been deleted altogether.
This was achieved mostly by increasing the diameter of the LP compressor, hence increasing the mass flow, and adding a second LP turbine stage.
The "B" engine was destined for the "B" Concorde which, thanks to several aerodynamic improvements, would have had increased performance and more range, allowing direct flights from Frankfurt and Rome to New York.
Concorde #17 would have been the "prototype" for the "B" model... sadly, as M2dude says, it was not to be.
