Also, from what I've read the Toasty Feet Insoles are thicker than what I can accomodate in the manner described previously. I don't want to lose the "loose fitting shoes" and the extra insulation they provide.

Anyway, I tore into my outdoor equivalent of everybody's bike component junk box looking for my hiking gaiters yesterday and stumbled across the unused insoles out of some Alpina NNN-BC ski boots I bought a year and a half ago. They're about 50% thicker, maybe 5 mm, made of what appears to be two different densities of felt, and offer some arch support as well.

I think I'll appreciate the added lateral stiffness offered by the elongated Superfeet heel cups more in the old xc ski boots more than the slightly stiffer pedaling platform they provide in the Lakes. I think I'll cut the bc ski insoles down to fit the Lakes and see how they do. It is, after all, a cheap experiment. It's not like the old insoles have been doing anything more than collecting dust.
