Alliances are all well and good, but it will never happen within the context of the setting as it stands. The Imperium is way too uptight about Xenos to make friends with races as friendly as the Eldar or Tau, much less sic a few hordes of Orks on the Tyranids.

The Necrons helping is about as likely to help as Chaos, and the Imperium would be just as likely to accept their help.

The only situation where any alliance could occur would require the human race driven to the brink of extinction before they even seriously entertained the notion.

Like all inevitable falls of mankind in the Milky Way Galaxy the 'nids will move slow, but never go away entirely.
