Hmmm I was thinking along these lines only the other day.
If it's carefully designed it should be able to provide a lot more than 15% extra thrust
The Russians made an early jet fighter that used a piston engine to drive the compressor and a combustion chamber like a conventional jet engine. The idea has a few advantages over the traditional gas turbine design, especially in model size applications. properly designed it should over double the thrust but you wouldn't use it as an afterburner it would have to have a proper combustion chamber and nozzle and would have to burn fuel all the time.
