For both performance and memory, each object adds some overhead. But the group object would seem slim in both respects, so I wouldn't imagine an extra level of nesting would make much difference either performance or RAM.
Images, however, are among the most RAM-intensive objects LC handles. Each exists at least initially in its compressed form, then in its unpacked bitmap form when rendered (width * height * color depth, possibly also + alpha width * height if PNG), and often both exist at the same time.
If there's a way to reduce the number of images, or their size, or their quality (if JPEG), you'll likely get much farther with reducing memory requirements than by removing groups.
