PACKRATS -- a COMPULSIVE HOARDING card game for 2-4 -- my first BGDF thread

Hey all!

I want to do a humorous, colorful card game themed on compulsive hoarders/hoarding (folks who hold on to crazy amounts of lord knows what/cram their homes to bursting).

Primary gameplay would revolve around management of acquired stuff. There'd be a constant flow/influx of good (and not so good) stuff. So, some queue management (Guillotine. Pecunia Non Olet. A hand of beans in Bohnanza.) and a lot of stacking and fitting (pile/stuff/junk management -- any non-dexterity stacking games I should look at?).

Each item/card would have size and weight information relevant to stacking and color-coding/other attributes relevant to end scoring. Possibly different player characters corresponding to the different colors/suits (codifying an unhealthy affinity for certain types of junk) -- such that they would compulsively HAVE TO take in a certain amount of awkward and/or worthless junk. ("It's a horribly awkward and fragile crossed lightsabers floor lamp and I DO NOT have space for it, but look... LIGHTSABERS!!")

Play to a certain point (don't attract social services!) and score for cramming in the most junk -- but there are many ways to vary/tweak this:
Set collection. Diverse collection (X of each color). Secret goal cards. Cramming small objects into drawers and cupboards. Filling up the space below chairs and tables. (a bag of 1632 twist-ties!) Overstacking and collapse of piles. Some possibilities for trading.

I want don't want the gameplay to be Action Card driven (a la Guillotine) but am thinking it should be more of an action point allowance/Stamina system. Moving X amount of weight from pile to pile costs X stamina/points ... pushing something back in the queue costs X. etc. (a 10lb bag of orange gummy bears! who eats the orange ones? orange things go in the leftmost cupboard.)

Right now the game glorifies the unhealthy hoarding... and I think I am okay with that.
I have some BAD packratting tendencies myself and well... at least it's not about brutal violence.

HOW CAN YOU HELP!
Any and all comments are very welcome, but I think the place I am most stuck is... the math of deck size. I have no idea how many cards to start with. I want play time to be something like 30 minutes, I think player mats seem necessary and would have maybe 3 base spots. Items should be stackable at least 5 high. So we're talking at least 15 cards per person plus it needs to be padded up to make it all less predictable. Should I just start with 60?

Clearly I have been kicking this idea around for a while. Long enough that it has too many different possible forms/variables in my head and is becoming a total muddle. What sounds good!? What sounds overly complicated? What makes it sound most like it is about unhealthy hoarding habits!?

Thanks!
