Hello... My name is Chris and I'm short....
Chris, you crack me up!
This may be a dumb suggestion, but isn't it possible to cinch down the last few inches at the foot of a regular mummy bag to give you a more snug fit? Even something as simple as a tight rope or bungee might work. My crafty wife would probably whip out her handy-dandy sewing machine and sew closed the last few inches of the foot area into the shape she wanted, but that's beyond my pay grade. I tend to think in terms of jury-rigging deficiencies rather than buying new stuff.
Just a thought - and maybe I'll think better of it after another cup of coffee . . .
