I've finished the first and am ready to turn the heel on the second. They fit well and are very warm, but are not streamlined enough to squish into my loafers.
Looks like Idea #2 will be put into practice soon. I'm going down a needle size and will do a striped stockinette heel flap instead of a slip-stitch heel.
The bed socks might end up a gift; I have a colleague for whom I haven't knitted anything yet, and these will fit her, too. Her birthday is in March, so she'd still be able to wear them for a while before it gets warm.
I'll be knitting this pattern again, too. It's fast and pretty, as well as a good way to use up scraps on worsted weight yarn. Maybe I'll submit this to Knitty for this year's fall or winter issue. They're ready in about 2 days (or less), so they would make good Christmas knitting.
