I could see Pteranodon Flyers being closed down and turned into a lengthy family suspended coaster around JP (using the TE plot and the current Pteranodon ride path would allow a nice 4-5 minute family coaster). This would get rid of the slow capacity aspect of PF and finally give JP something to do during fall and winter.
It could be a wooden coaster or something like Big Thunder/SDMT, but that might come across as a knockoff. I wouldn't mind, but again, there's not much room for a sizable coaster unless they ruin the JP and HP skylines by having steel track fly over that whole section.
Add the Discovery Center dark ride and maybe a unique flat to make up for Pteranodon being absorbed for the family coaster to keep the attraction count as high as possible. Equal to New Fantasyland without having to hype anything up.
As for Puss in Boots, keep in mind, they're just building the track currently. I'm imagining it's going to be a step above a kiddie coaster in terms of thrills and theming. I'd wait to see what the finished product looks like before calling it a step down.
