Here's another version that should work with what's in your army right now and is pretty close to an what I'd consider an IH Mechanized force.
Iron Hands Clan, Tacticals, Rhinos [300]
Iron Hands Clan, Tacticals, Rhinos [300]
Dreadnought Phalanx, Venerable Dreadnought, Hunter [375] Garrison, Forward AA
Dreadnought Phalanx, Great Council, Hunter [375] Garrison, Forward AA
Predators [250]
Bikes [200]
Whirlwinds [300]
Strike Cruiser [200]
Warhound Pack, [500]
Storm Talon [200]
What I really like about this is the flexibility it gives as you can choose at setup to pod the clans / dreds into play or garrison and use the nasty 24BM swallowing clans in tandem with each other. When podding, especially against guard, force corner setup, bring the the Cruiser in T1 with the orbital barrage right up on them all bunched up, follow through with pods and shock assault. This is very Iron Handsy almost to the point of the the same strategy taken at the Isstvan V Dropsite Massacre so take that how you please

If guaranteed not to pod, then switch to
drop the strike cruiser, give each clan a single razorback (plasma) and/or a Land Raider and get the 26BM (that's insane)
