1500 pts DE versus Suit-heavy Tau

Hey folks - i thought I'd run this by you guys. I usually play against my cousins suit-heavy Tau force, which usually fields something like 3 units of 2-3 Crisis with Missile Pods and Plasma Rifles, 2-3 units of 1-2 Broadsides, 2 units of 12 Fire Warriors (in Fishes) and a big unit of Kroot. I think this will be a great army to use against it, and a bonus is, its what i actually have (and almost painted!):

Baron Sathonyx
2 Haemonculi, both with Liquifiers, Scissorhands and WWPs
4 Blasterborn in Venom with 2nd SC, Nightshields
7 Hellions, with a Power Weapon Helliarch
9 Wyches, Hydragauntlet, Hekatrix w. Power Weapon, in a Raider w. Darklance, FF and NS
2x5 Warriors w. Blaster, in Venom w. 2nd SC, NS
Cronos w. Spirit Vortex
Talos w. Chain Flails and TL Haywire Blaster
Razorwing w. Splintercannon, NS and FF (unsure if i want to give it Darklances or Dissies)
- 1495 pts total

What do you guys think?

Considering how much mobility you have the Cronos and Talos don't fit. They are slow compared to the rest of the army and can be picked off. The Cronos especially due to its short ranged weapons.

Notice those 2 Webway Portals?
Anyways, the basic idea is that i start with the wyches and Trueborn on the table, with a Haemonculus in each - they move forward 12" at different sides of the table, where the Haemies will pop their Portals down for the Cronos/Talos and Hellions (if i reserve them) to charge out of when they become available

(the Warriors, Hellions and Razorwing are either kept in reserve, or start on the table, depending on what i feel like/is tactically viable)
