Circumventing 22nd Amendment via Resignation

[SPC]

Suppose that the Vice-President assumes the Presidency a few months short of two years after the inauguration (similar to Gerald Ford in 1974). Two years later he wins re-election, and six years later decides to run for a second full term. Would this be permissible so long as he submitted an intent to resign prior to the six-year mark after his inauguration?

Now suppose that instead of a few months that the inauguration took place sometime in late December or early January. Would it be permissible for the President to receive votes in the Electoral College provided that he did the same? If so, what would occur if the President rescinded his resignation after the electors cast their votes?

Okay. However, if Gerald Ford were to resign on August 7, 1976, he would be permitted to run for re-election in 1980 assuming he wins in 1976?
