With 55 points you can take quite a few models that work well with multiple masters.
Something like:
2x Stitched Togethers (10)
3x Alps (9)
2x Insidious Madnesses (4)
Lelu & Lilitu (14)
Coppelius (9)
Then take totems and Master Specific stuff:
2x Daydreams (4)
Poltergeist (2)
Sorrow (3)
That'll let you have a competitive crew loadout for Pandora, The Dreamer and a decent (not perfectly optimal) crew for Zoraida (Zoraida summons the Voodoo Doll, so I'm assuming that doesn't count towards your 55 points). Also, on the point of summoning, LCB/The Dreamer can summon another Daydream if needed and Coppelius and the Alps can summon more Alps too.
Now, I will admit you are missing the big heavy hitters like the Mature Nephilim, Teddy and the Bad Juju, and you are missing the speed that Lilith brings to the table. You do however have some pretty heavy damage potential from the Stitched, Lelu and Coppelius, and you get all the fun control elements from the Alps, Lilitu and the Madnesses, while having 3 different Masters to choose from.
