Dumb question, but is the A1200 bootable at this point? Is there an OS installed, etc?
If so, and you can get the ADFs over to it, you can use tracktool to make WB disks from the ADFs. Remember to either use 720k disks (preferred), or tape the HD hole (the one without a tab in it) before formatting / imaging.
Otherwise you're kinda stuck unless you have access to another Amiga or invest in a CatWeasel.
