My GTX 960M clocks the same frames with BP injected, it must be that you have your programs/drivers poorly optimized. Check for updates for your drivers, as well as maybe cutting back some intensive graphical features such as skeletons (for the hack) and anti-aliasing (for the game). These aren't guarantees but simple suggestions to get a little boost to frames.
As for rebuilding the software of Big Packets completely, I can say without a doubt in my mind that will never happen. If you understand the fundamentals of coding you'd understand that everything is built on iterations and to "start from scratch" for a small boost to fps is asinine.
