When was the latest date that alt. names for North and South America might have become common?

[Alt History Buff]

Just as it says:

Was there any point (say, post 1750) that North and South America might have officially been termed something else (Columbia, Peruana, Mexicana, etc)?

Or was it too late by that point as the names were established enough?

Thanks.

Probably too late when names had used 200 years.
