Nope, because ONE set is not TWO Sets.
 In the set ℚ there are as many indices n/1 as are indices n in ℕ. If indexing all fractions was possible, it was possible with indices n/1. But it isn't.

But what you can use belongs to ℕ_applied. Otherwise show a natural number that completes the bijection, i.e., which has not infinitely many pairings on front.

You can use only a small minority because almost all remain unused:
∀n ∈ ℕ_used: |ℕ \ {1, 2, 3, ..., n}| = ℵo.
Which ones were unused by e = 2*n?

You "Complete" the bijection by showing the infinite sets map one to one by the formula of the bijection.
 I show that Cantor's bijection fails.
Nope, you show your misunderstanding of Cantor's Bijection fails.
