Hi, welcome to the forum, dukeofyork!
It's always good to see a Duke Sliscus list, but I don't think you'll want to Deep Strike. You would be dropping in about half of your transports Turn 2, but then what, as you can't assault on the turn you Deep Strike? Hang out in the boats? A much more precise way to get your assault elements to work is to maneuver them 24" Turn 1, then move 12", disembark, assault (and run if you're not a Grot). Even the Ravagers want to be on the field to start if you're going first, or can hide them well. The all-Deep Strike list is fun, and is my current army of choice, but it's all about close-range shooting.
With that out of the way, I'll give my suggestions for your list.
1. The Haemonculi may not want Agonizers- oftentimes you split them from their Wych unit to allow the Wyches to run, so equipping them in cheapest fashion is good- a Liquifier and/or a Venom Blade, for example.
2. If you can fill your 6 Troops slots by adding more Wych squads, try to do so. However, it's a balance, because assault units need the right tools and numbers to get the job done. I would give most if not all of your Wyches Haywire Grenades, and give each unit a Hekatrix with an Agonizer. Their Raiders could use Flickerfields, (your Ravagers definitely need them)
3. A popular option to fill Troops is a minimized Wracks squad. Typically 3 Wracks in a 2-Cannon Venom, you could place them in a Raider instead for another Dark Lance. 90 points per Lance looks good when you get a unit that claims your homefield objectives in the bargain.
4.To get even more ranged anti-tank, the Grotesques and Incubi would be the first things I would cut for it, in that order. You have power weapon support from your Hekatrixes, and the utility of high Strength attacks can be emulated against Monstrouc Creatures by the Duke's squad or your Haywire Greandes against vehicles. More Trueborn with Blasters in a Raider with a Flickerfield would be great, though Reaver Jetbikes are anti-tank that can be anti-infantry, and they use combat drugs.
Those are my main thoughts. You shouldn't worry about the new rules until they are here, in my opinion. Just enjoy youself!
