What should I cut to make this a decent 3k list?

What do I need to make this a balanced 4k/5k list?

I don't do MS in my lists, but your list is pretty similar to what I bring for 3rd company.

3k: Seems like you can cut out either eidolon or lucias depending on what you're feeling for that game. Having both in a 3k list is a bit too overkill in my opinion. To be honest you do have a good tool kit to pick from for 3k. Just need to play and see what works in your group

4k: Perhaps throw in a Deredeo with lascannons for some juicy AT. Especially if there's tanks in your meta. Perhaps a cbeam predator if you want something destructive but fun.

Some suggestions would be trimming down on Sunkillers. I personally think 5-7 is a good range to bring for most 3k lists. The reason being is the 2+ to hit makes up for how expensive a 10 man is. For 4k, I feel like 10 is fine unless you're trying to squeeze another unit in.

I would recommend just playing and seeing how it goes. I feel like you have a good core army that you can plug in or swap a couple units depending on the lessons you learn.
