I've tried it with 10 Evocators instead of the Sequitors too.
Bit hittier and another wizard for battleplans where that matters for scoring, but I think the bigger blob of sequitors is better most of the time.
I've also got a version with neither and just pump up one of the Liberator units to 30, which loses a drop, but it takes the list to 1970 so it loses out on an essential command point, so I've pretty much discarded it.
BTW, the Judicator squads are equipped that way purely because it's the models I currently have. When I'm able to get some more, I'd like both squads to be crossbows with a shockbolt prime.
