The time enroute saved by clipping your wings will be spent changing tires, and you won't have much baggage area left for a tent. I understand wanting the best of both worlds, but my advice is to keep it simple. Get all the speedster streamlined components, but keep the standard wing, which is fast enough and plenty nimble, and also lands well at high DA in the backcountry.
The 914/Airmaster is a great setup. Spendy, but worth it. You'll love it.
