Hmm, that'd leave flat shells, which ought to bind up nicely.  Good idea.  
I've gotten so used to double tying my hikers now that I think I prefer it.  I also think that with that pair I prefer to keep the cordage whole, the idea of disassembly is abhorrant for some reason.  However for other footwear applications I will heed your advice.
