Still, that may be one route to take. Scarpa's Thermo Cerro Torre ($375but currently available online from Scarpa for $245; www.scarpa-us.com) is an excellent, light, insulated mountain boot that takes crampons. I've worn the non-insulated version and loved it. Very comfortable. Not waterproof in the sense of having a waterproof liner, but extremely water-resistant. You might also try a light plastic boot, such as the Koflach Degre ($245; www.koflach.com). That'll work like a charm so far as the dry-warm combo goes, but will be somewhat heavier and not great for extended hiking.
The best alternative, I think, is to buy a more traditional hiking boot and winterize it. Montrail's Moraine ($235; www.montrail.com), for instance, is an excellent, crampon-compatible hiking boot. Again, while it doesn't have a Gore-Tex or similar inner bootie, its thick, one-piece leather is inherently waterproof. Or, try Tecnica's Stratus Bio-Flex GTX ($200; www.tecnicausa.com), which does have a Gore-Tex liner. Then, add an insulated insole, such as the Insolator ($8 from Campmor.com), to prevent the cold from coming up through the sole. Fit the boot to accept a pair of good-quality sock liners, such as SmartWool Merino Sock Liners ($10; www.rei.com), as well as a warm main sock, either the SmartWool Expedition ($12) or an insulated sock such as the SealSkinz Chillblocker ($50; www.danalco.com), which combines a waterproof material with a fleece lining. These socks actually would turn any good-quality boot into an acceptable light winter boot.
Of course, you'll also want to wear a gaiter to keep snow and water from entering the top of the boot. The classic is Outdoor Research's Crocodile ($58; www.orgear.com).
So there you go. Good luck, and I hope your winter is better than your summer has been!
