Here are all the "saber" mounts turned into a Dawnsaber/Zulian Tiger.
Just throw one (or all) of these into your data folder.
Patch-a = Black War Tiger
Patch-b = Frostsaber
Patch-c = Mistsaber
Patch-d = Stormsaber
Zulian.zip
Dawnsaber.zip
EDIT: Added Zulian Tiger edits to the list. Will add the purple saber once I reopen all my patch files.
(Something to note, I kept the Zulian Tiger's eyes red instead of green because that's what the Dawnsaber's were, I was going to change them but I really liked the outcome, so the Zulian tiger will have awesome red eyes :P)
