You've got a lot going on here, which I think is why you aren't getting a lot of traction in asking for replies. You've also got a few units that really don't fit into any of our 'meta' lists, so trying to rearrange stuff to still make a solid list will be tricky. I'll do my best to sort through it, though - keeping in mind that I'm not exactly a list building wizard, as I've only played a few games myself.
For starters, it looks like you've got artifacts on each of your heroes - that's not how artifacts work. You get one artifact for your whole army in matched play, plus an additional artifact for each battalion you've got (you don't have any).
Next, I'd suggest remodeling your Fulminators into 2 more Concussors. Desolators and Concussors tend to be the best Dracoth choices, and regardless of what you choose they'll be far better as a single unit, so you can give them all the Castellant buff and make them extra tanky. Since you've got 4, Concussors are probably as good/better than Desolators - if you were going for 6, I'd say you for sure want Desolators.
So with that out of the way, given that you've already got 10 Liberators and 10 Judicators, you could consider trying the Skyborne Slayers battalion by adding a unit of Protectors, a unit of Decimators, and a Lord Celestant on foot. That'd be two Paladin boxes and a single Lord Celestant, which wouldn't be that much of an outlay to get 2k points on the table. I'd probably go for the following as a final list:
-----
Allegiance: Stormcast Eternals LEADERS
Lord-Celestant on Dracoth (220)
- General
- Command Trait : Staunch Defender
- Thunderaxe & Thundershield
- Mount Trait : Pack Leader
Lord-Castellant (120)
Lord-Celestant (100)

5 x Liberators (100)

- Skybolt Bows
OTHER UNITS
5 x Protectors (180)
5 x Decimators (180)
4 x Concussors (480)
BATTALIONS
Skyborne Slayers (190)
TOTAL: 1990/2000
EXTRA COMMAND POINTS: 1
WOUNDS: 108

Not sure what artifacts I'd go with, as this is just an airball list that I came up with on the fly. As an army it would be unlikely to blow anyone off the table, but I could see it being fun to play. No magic or prayers, but very fighty. You've got a sturdy mobile anvil with the LCoD and Concussors, the ability to drop basically anywhere on the table and immediately charge the opponent's vulnerable units with the Slayers battalion, and a bit of ranged support to stand on objectives in the Judicators. Given what you've already got, I think it's probably not a bad list to aim for, as it uses literally everything you've got other than the Lord Relictor.
Happy to hear feedback from anyone on it though, as I know others here have talked about using the Slayers battalion before with some success. Thoughts?
