Not an easy question, as predicting snowfall for next year is impossible. I advice you to do some research now, but make the decision based on the amount of snow in januari if you can. A lot of snowbums go live in a camper van where the snow falls, but with a family this might not be as easy.
February / March is already quite late in the season, so Kleinwalsertal would probably not be the best option in my opinion. Those alpine foothill areas are more suited to early and mid winter, when they recieve more snow.
Late winter mid- to high-apline would be a better bet. Look for a nice inner alpine region that preserves the snow but can still catch some freshies.
I'm not an expert on Austria myself, so I can't help you there. Montafon does get a lot of snow if it's a winter with lots of north west stau, but that's not always the case. It's not a terrible idea though, less crowded than st. Anton.
Or you could live in Galtür, and buy the Snow Card Tirol. Galtür doesn't get as much snow as Montafon or St. Anton, but it's nice and cold there and a short trip to other places with the Snowcard it would be cheap. And for touring you have lots of options closeby including to Montafon, south of Ischgl or even Switzerland.
Anonther option is to find a place in Italy. If it's winter with lots of snow from the south you're golden. If not it's only a short drive away to the high alpine for touring, and the weather, food and people are really nice. I used to live at Lago Maggiore, it's a very nice climate and you can go touring on the Simplon anytime as there is always snow up there. Airolo/Andermatt and B**** G**** are not that far away either. It's just a nice place to live with a family, that's why I would recommend it. Bring a mountain bike too.
But anywhere near a tunnel or mountainpass that crosses the Alpine divide would work. This means you get to ride with snow from the south, or north and that's the key. Make sure you find out if the tunnel is cheap, or the mountain pass closes in winter though.
