ok no, without a doubt if this alternative universe was exactly the same as this one, only that WS and WP were un bundled, Wii Fit would not sell as many copies as WS.
Infact there is most likely a significant snowball effect arising from WS use and popularity that allowed WF to become the proxy sequel to WS and sell as much as it has. This also explains why WM is not part of the Wii specific subgenre in terms of sales.

“When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking. ...if the employees were always minding themselves to do whatever the market is requiring at any moment, and if they were always focusing on something we can sell right now for the short term, it would be very limiting. We are trying to think outside the box.” - Satoru Iwata - This is why corporate multinationals will never truly understand, or risk doing, what Nintendo does.
