Not tried it, but it is said that the Titania Box is great with Lucius, mixed with Master Queeg to get the (0) actions, maybe Rougarous in the mix.
To be honest, what you have is similar of what I have and works well (Nekima and Doppelganger, powerful minions like the illuminated).
I normally add an Austringer too, is one of the great guild minions even with the errata and allows you to capitalize on the low model count (no summon) for positioning and interact.
