Your best bet might be to check the HH team optimizer and see if there are any suggested team that someone else got to work.

But if there is, it's probably gonna require INSANE speeds.

You don't have any of the major freeze champs: Gnut, Blizaar, Croidan, Neldor, ...not even Yakarl?

no sadly I don't have them

It can be done without Freeze but it's tough.  A core of Martyr / Mithrala / Coldheart can work.  Essentially you use Martyrs Counter to drop the shield, Mithralas cleanse + general support and CHs nuke + heal reduction.  Add in someone like Longbeard for damage and a good wave clear option and you could give that a try.

I'll give it a go today
