What if Protons were heavier than Neutrons ?

[Widdekind]

In reality, neutrons are heavier than protons, and so, if free, the former decay into the latter, with a half-life of 11 minutes:

 

[math]n^0 \to p^{+} e^{-} \bar{\nu}_e[/math]

 

But, what if protons were heavier than neutrons ? Would that then mean, energetically, that all Hydrogen atoms would "collapse decay" into neutrons ?

 

[math]p^{+} \to n^0 e^{+} \nu_e[/math]

(what if ?)

 

[math]e^{-} p^{+} \to n^0 \nu_e[/math]

(what if ?)
