Metropolicity is doing Leathermans only right now, but there are people at MultiTool.org who you might be able to talk into doing a build for. You might look at http://forum.multitool.org/index.php/board,16.0.html, particularly the stickied items at the top.

You might also decide to use a different form factor. The LM Wingman and Sidekick are ridiculusly easy to take apart, and Home Depot has one of them on sale for like $20- take it apart, and put it back together without knife blades and without the plier head, with some of the tools from other handle in the head even if you are willing to get fiddly.

Or buy yourself a pair of good tweezers, a pair of good, small scissors, a p38 can opener, and a cheap multibit screw driver small enough that all this fits in an altoids tin. Add a couple wire twist ties, a few paper clips, maybe a needle or two with some thread on them, a few tooth picks and a pair of nail clippers if there is still room. You could do that for the cost of a Vic Spartan or Tinker.

And I agree, being able to pick layers and combinations from Victorinox would rock.
