Nintendo Land is the Wii brand improvement Nintendo went for, and it is a better game just not as new or viral as Wii Sports was.
Wii Sports Club retail version should have never existed, the game's only main advantage with its predecesor is online play which goes hand-in-hand with the digital title. The pedometer was the only addition for WiiFit U; they had an offer last year when you coupled a Fit Meter you could keep the trial version forever (and that's what I did). Yes, both of these low sellling retail games had trial digital versions.
I do like your take on Wii Sports, but I would have continued with Wii Sports Resort and gone for Wii Sports Land via the Go Vacation route. Add new sports and maybe make some interesting uses of the Gamepad when they add something, but let people free to roam around Wuhu Island!
I've talked about Wii Sports Land before, that together with Big Brain series and Art Academy. Which takes us to Art Academy.
Art Academy, we saw it when the WiiU was first announced, a title that should have been available since launch, it gives purpose to the Gamepad! Miiverse wouldn't have been the same without the art... it's 2015 and the title still not out...
Just for fun, here was my own take on Art Academy and educational software.
