The Cab & Translite it'd be okay either way for me.

But on the playfield I'd definately prefer ZY. Better sneak in some lively nonsense in the inbetweens all over the playfield instead of filling the empty spaces with some patterns...

That said it'd be totally fine for me to not completely cram the whole playfield with art/ assets and just use some plain colors in areas.

In that regard the best Franchi Playfield is the one Kevon O'Connor composed, wich is BM66. It looks more classic pinball but with Franchis awesome art assets.

This is the only complaint that will really hold up/ you can't neglect (since we've not seen what the toys/ the house does, if the game has lots of subways, will be free, what the code is etc. - so impressions still might wildly change).

Elvira is about... Elvira. And her... "Assets".
So where is she?

I get the "movie" theme the game has but she could at least be lieing on the couch, "moderating" things.
That would fit the theme.

No doubt, but I like some art on the playfield nontheless.

Lol. That would be one heck of a Pro!!!

2 Motorized entrances, motorized bash toy, subway, physical ball lock in trunk, 4 small gargoyle kinda bash toys, interactive mansion with diverters and motorized roof...

I'd guess a Pro'd only have the entrance Flap lifting and a diverter so that the mansion does at least do something.
