I'm a big fan of the zoraida/ophelia combo so hopefully i can offer some of my thoughts...
All your options could work well, though I probably wouldn't go with papa loco, i find that pere fills that spot nicely enough and if they both blow themselves up, while they do a whole lot of damage, you're left with a big hole in your crew.
The terror tots make great objective grabbers as they're fast and they can also hit pretty hard if you get that flay trigger off (min 3 damage on a 3ss model? sounds good to me).
bayou gremlins work great with ophelia for some cheap ranged power, or you might like to try her totem the young lacroix for the same price. While not significant and thus not good at objective grabbing if you need firepower, using magical extension to cast 'right between the eyes' is always a good choice.
Of course, don't forget about all the neverborn stuff you can take too... While you can't take wicked dolls or other special forces stuff, one model that almost always appears in my lists are the silurids - very fast and if you've got something like deliver a message, almost too good not to take. ((0) 9" leap in, (2) deliver the message, (0) 6" self preservation out)
And don't forget the classics, lilitu and lelu.
Hope that helps in some way, look forward to hearing what works for you!
