That'd also work, in which case I can leave the shape shifters on their planet a while longer since they hwve warp capabilities and have heard of the Borg, never seen them, but heard of them.
Except how would Romulans or Cardassians have ended up there?
The point of them getting lost in a new space is to find species who can help against the Borg and possibly be an unknown to the Borg collective
