I have tried cross-breeding many different types of multitools. Is it possible without "major surgery"...oh sure. A little filing here, a little bend there...it can work. But unfortunately, the result is rarely as good as the end product was in my mind. The major problem I have had is that there is no standardization between manufacturers...so the implements and other parts are different thicknesses, lengths, use vastly different locking mechanisms, etc ad nauseum. Within the same brand, i.e. LM to LM or Gerber to Gerber...a lot of tool swapping is very possible with very little effort. You would have to do some pretty fancy welding and you'd have to be VERY careful not to ruin the temper of the hardened parts, lest they become "soft" later. Just my experience, YMMV.
