I have the complete pedal set and am very happy as they are comfortable and give a very good "feel" and control, specially the accelerator. However, it does not move the pedals closer. Maybe the accelerator a cm or so (compared the rather uncomfortable OEM roller pedal), clutch and brake is pretty much the same as before. Cain at Wolf is one of the few that really develops new stuff that works, if he is working on an extension kit, I guess it will be more that adequate when launched.
An organ add-on pedal might solve your problem, though. I have not tried it, but I did not like the design - introducing one more moving part in the system. I feared it would be less "direct". But no personal experience, just a hunch.
