Smaller Playsets that could work in MOTUC

Grayskull is coming and I'm skipping it... (Logistics) but all signs seem to point that it'll be THE ONLY Playset we'll get. No Snake Mtn. No Frightzone, no Starship Eternia, no Nordor, etc.

But there's a few "Playsets" that Mattel COULD get away with or at least as Diorama Pieces.

Slime Pit:
The Evil Horde's secret weapon for Universal Domination... If you look at it it's slightly Taller than a normal mailer... I'd say about as tall as the length of a 2 pack mailer (when assembled, theoretically speaking) Maybe half a normal Mailer Deep and in theory it SHOULD be cheaper than Castle Grayskull to make. It's pretty much 2 Sheets of plastic turned into the back and floor (not sure if they are Thermo-molded or injection molded...)
and 3 extra pieces for the claw and Dino head. Any extras like sculpted slime drippings in Glow in the Dark plastic are welcome but not Mandatory. In theory this should be inexpensive to make. Not only it's an evil playset that Many want, but Mattel could make it quite easily in comparison to Snake Mountain, who'd require a lot more resources and the Horsemen's time... Personally I wouldn't be surprised if the Horsemen already have figured out how to make one... Or have sculpted one just for kicks and to kill some time.




Whispering Woods:

This will be the only Princess of Power Representative here. Mostly because none of the Crystal Castles could be made justice in a smaller scale (Though a Light Hope chamber diorama could work)
but The Whispering Woods seems small enough to work.
Do you remember the Kenner Endor Playset, or it's reuse as Sherwood forest? Well, something along those lines.  Maybe it should come with pieces to make2-4 Trees,(either 4 Medium Trees about 1.5 figures tall or 2 Trees taller than Tytus... the big blue Trees with the candy cane pattern on their bark/) a pair of shrubs. (Maybe with a "secret compartment" for Loo-Kee), a clear stand that plugs on the trees for Kowl.  Then you could "Army build" and make a bigger forest. If Mattel plays it smart enough, they could make "Whispering Woods Stands" to further expand the concept. Toss in some Twiggets (who'd very likely end up as nearly statue figurines) to the mix and watch the POP fans eat it up!

Eternos Palace Courtyard: 
Yes, I did mention how you could make one in the Baking Goods Stores can give you Diorama Pieces  Rant but a custom made item will never be an official one. We have an Eternos Palace King Randor, so getting the Eternos Palace in MOTU seems like a priority... (After Snake Mountain, Fright Zone, and all the other Playsets that had a toy previously, which include the NA and POP Playsets) Since the King and Queen cannot set their butts on the thrones, the Throne Room is out of the question. Not to mention that half of everything that happens on Eternos tends to happen at the courtyard.

I know this list is small, but there isn't THAT many small playsets that they could do. Out of these, the only one I see that MAY have a Glimmer of Hope is the Slime Pit... Mattel wastes resources on stupid-ass stands that don't work that could be better used for actual dioramas... err... playsets...
