Although,

If you use similar JPEG compression ratio's I think you might end up getting similar (although not exact) images. Because the source image is already compression, it has already reduced the frequencies in the image, so when the image is compressed again, the image is already at that frequency level.

It is my understanding:

if you open a JPEG file, AND either

1. write it as a TIFF (using JPEG in TIFF compression, with compression turned on), you are going to get a TIFF that looks much worse than the original JPEG 2. write it as a TIFF with compression turned off, you are going to get a file that is much larger than the original JPEG.

In this case the original file is a TIFF though... Can I somehow insert that "as is" into a new mulipage TIFF without having to deal with making any changes to the way it was originally compressed in the single page TIFF?
