Let's face it. Guardians of the Galaxy doesn't fit at all with Disney Parks...I would still find GotG a slightly weird fit in the MK, although much better than in FW. It's not a complete clash, but somehow it doesn't feel an organic fit either.
It's a pity the new DHS lands are single-ip driven. A Marvel, or Marvel-esque, land would work there.
Mickeytouille would be just perfect to anchor a new Big Five Land as replacement of Dumbo Tent Land.
