Lots of great comments. I appreciate them.
@David -- Good stuff. It sure looks like no one sells anything "off the shelf" so I may have to cobble together something (or do without). Your thoughts are appreciated.
@Will -- I might have to check them out. I rarely go that far north, but I have been to Ferndale -- not far from Bellingham, where I used to live.
@Richard -- Excellent find. I ran across that in my research as well. I don't think they make them anymore. Basically, half way to where I want to go :).
@Mitchell -- It is more bulk, than weight (although weight too :)). A single pole can be easily carried in the side of my pack. I carry my trekking poles this way all the time. I don't cover the tip or anything (very little danger of poking anyone, really). With an ice axe, there are more points to cover, and carrying it is just a bigger hassle. If a single pole (alpenstock, if you will) approaches the weight of a Corsa, then chances are, it is longer. If it is longer, then it can be used as a trekking pole, or if nothing else, works better for self belay (as David pointed out).
Oh, and I'm afraid I don't own avalanche gear. I simply avoid risky terrain when it is risky. The Northwest is lucky that way, really. Unlike some places (Rockies) our nice weather days are usually very stable. Our unstable days are usually socked in. So, when it is dumping, I ski someplace safe. When it is clear, I ski somewhere pretty. In the Spring (when the snow has stabilized) is where I do most of my ambitious stuff. The trade-off, of course, is that unlike the folks in the Rockies, I rarely ski beautiful powder under blue skis to big peaks. It's usually one or the other (great snow or great views).
All that being said, I really like your shovel idea. That may the best option. If I can find a good second hand shovel, it might work really well.
