Yes.  This is the way I would probably do it, although there are a variety of solvents suggested for liquefying clear silicone.

What ratio did of solvent to silicone did you use.  I've seen rates ranging from 3 to 2 (60/40) to 3 to 1 (one quart solvent to 1 tube silicone).  I would think the thinner mixture would be easier to spread and would more readily seep into the stitching.

I've seen a variety of youtube videos of individuals taking non-treated nylon (and other materials) and dunking it in this mixture to create their own silnylon (etc.), but I've also seen photos of sil tents going up like a torch.  I'm assuming that you would use the least flammable solvent you could get away with (although they all seem to be flammable at some level) and let it evaporate as much as possible.
