Doug,
Everyone has different aptitudes, but for me - playing the guitar has never hindered my kb chops. In fact, I learned to play drums years ago to improve my bass playing. There are many interactions that "make sense" between different instruments. Playing guitar can open your mind to better voicings and possibly, better technique on the kb.
If you let the guitar slip away, your fingers will soften and you'll have to start all over again ..... keep it up and put your highest energy level to the task that needs it most.
