I also did not want to change the original message outbound at all. (if there were any recipient re-writes, indication it was re-directed, etc.) Also redirection *could* cause bounce if for some reason there was a problem with the dummy account.

that's how I do it too.

Split your shadow_copy_out router into two halves
the first have uses the redirect router, your conditions and unseen
flags and rewrites the recipient name to some sort of nonsense address
eg: "data=shadow_copy@fakedomain"
then specifies "redirect_router=shadow_copy_out2"

The shadow_copy_out2 router goes below the final router in your
routter list where it won't normally be run and does the other parts
of youur shadow_copy_out router, but is not flagged unseen

So exim does the unseen redirect once, runs the shadow_copy_out2
router once and the transport and records "shadow_copy@fakedomain"
as being delivered, the second time trhrough the routers
"shadow_copy@fakedomain" is already delivered so it stops that path at
shadow_copy_out2 and only does the specified recipient copies.
