Games don't get made unless the developers have the money to make them. Any potential success SFV had would have been meaningless until Capcom had the money to make the game in the first place. Capcom didn't have enough money to make SFV and pay its employees and keep the lights on. Sony stepped in and bankrolled SFV with the obvious expectation that it would not show up on Xbox One, Wii U, or Switch, at least until x number of years had passed.
I doubt that Platinum similarly has the money to make W101 on its own. That said, that point is moot. Until Nintendo relinquishes its rights to W101, it ain't happening.
You know there is a difference between being in bad finances and not having money to make new a title. Where exactly did you get this information that capcom could literally not afford to make new SFV game?
IF (strong emphasis on if) this was true Capcom could definitely take out a loan to finance a new safe investment (one of their biggest IPs, SFIV sold 5m the previous gen), but I would at least understand them looking for other investment instead of a riskier loan.
