well, I would probably have rethought my list if I were you, firstly though I would probably try to limit myself to an army wide idea, for example msu,fast, MC or skimmer spam. While you cannot take more than one of each there are many things that are similar.
Here are some combinations I would look into if I were you:
Fast army(speed)
What is fast in each section?
- HQ = farseer and warlock, autarch with improved mobility.
- Elite = running banshees or infliltrating scorpions possibly but still very slow.
- Troops = windriders, fill out with rangers possibly.
- Fast = shining spears, warp spiders, swooping hawks
- Heavy = wraithknight if anything
MC spam (durability)
- HQ = Avatar, phoenix lords or eldrad (spiritseer to unlock wraiths as troops is good)
- Elite = Wraithguards and wraithblades (double up for troops?)
- Troops = Wraithguards and wraithblades, possibly windriders.
- Fast = shining spears if anything
- Heavy = Wraithlord, wraithknight, artillery
Skimmer spam (lots of AV)
- HQ = nothing really, just grab something cheap you can stick in the serpent or falcon.
- Elite = ignore this section
- Troops = anything in a wave serpent, 5-6 avengers in the falcon.
- Fast = crimson hunter, hemlock, something from IA books or such, if not possible: vyper.
- Heavy = Falcon, fire prism, night spinner.
MSU (multiple small units)
- HQ = 2 autarchs/farseers on bikes, 1 mantle, 1 wing.
- Elite = 5 scorpions, 5 banshees, 5 harlequins, 5 fire dragons
- Troops = 5 avengers, 5 rangers, 3 bikes.
- Fast = 5 hawks, 5 spider, 3 spears (possibly add 1 hawk for larger blast)
- Heavy = 5 Reapers, 1 artillery piece, 1 walker.
You can of course combine some of these, the MC/skimmer or fast/skimmer combinations I think will work quite well.
As your list looks like now, you have a target for any kind of weapon your opponent may bring.
