On a serious note:No

Not only are you wrong about them selling bad, and there are several cases that proves you wrong(Monster Hunter, Bloodborne, Souls Series, Resident Evil, Final Fantasy, Persona 5(most likely),Nintendo games in general, Metal Gear Solid 5,and so on), but making the same franchises for smartphones wont necessarely make them sell more or more popular.

So yeah..... bad idea.

You have to factor in how much they spent making these games and how much time was put into it. Capcom was very dissapointed in resident evil 6 sales and FF lightning returns sales was mediocre. Those games are on a huge decline just like Street fighter.  Even Konami the makers of MGS5 are leaving the console industry for mobile.
