Hi!

You can create a composite image from your unaligned images, then
copy-paste one channel. After pasting, you can click and drag to whatever
arbitrary position you want. Make sure you activate Composite mode in
Channels Tool (Ctrl-Shift-Z) so you can see the other channels while you
move the active channel.
