I don't agree with the crop theory. You will not make as good a print of a bird by cropping 1/32 (or whatever) of your full frame sensor, with a wide angle lens attached, as I will by zooming in on the bird with my cheap Canon SX230HS travel zoom, even if your full-frame camera had similar pixel density.

In fact, it would be identical if the FF lens were as sharp as the compact lens.  That is, if you had a FF sensor made from the same pixels as the SX230HS, shot a scene at the same focal length, f-ratio, and shutter speed, cropped the FF photo to the same framing as the SX230HS photo, then the photos would be all but identical so long as the FF lens was as sharp as the SX230HS lens over the area of the crop.

For starters, you won't be able to stabilize the image enough to take advantage of the resolution you need.

Huh?  The effects of motion blur and/or camera shake would be identical.
