Again depending on the seeing, you have hit upon a technique not dis-similar to that used by planetary imagers i.e grab lots of short exposure frames and stack them. Each indicidual frame is statistically likely to have a small wavefront error, compared to one equivalent long exposure ( tip-tilt guiding can only do so much)

It's a high resolution technique that clearly can be used for deep sky, the only down side I could see would be noise supression (particularly with small apertures or if you shoot through a filter or ) and the ultimate depth of the image.
