I would try making sure the saddle is adjusted properly, and spending some quality time on the bike getting used to it, before making a radical change like that.
You'll bring your pedals 1" closer to the ground, which is a BIG difference. Some people won't be bothered by it, but you'll need to be really careful to keep the inside pedal up in turns. I once landed flat on my face after clipping a pedal in a turn (while standing out of the saddle), not a fun experience.
As pacificcyclist mentioned, by lowering the axles without also changing other variables you will also radically change the handling. Your bike will have a lot less of what's known as "trail", which means the handling will be much quicker and less stable-feeling. Seasoned road-bike riders might find it preferable, but most beginning cyclists would probably find it twitchy and confidence-robbing.
And also as pacificcylist said, if you don't have disc brakes you won't be able to convert to 24" wheels (unless you also convert to disc brakes -- which may or may not be feasible depending on the age of your Paratrooper). If you do have discs you will be able to do it, but it still won't be cheap. No one makes a prefabricated 24" disc wheelset, so you'll need to have a custom wheelset built. Figure on at least $250 or so for that.
