Already done a long time ago; see Algol 68 (Score 1)

Anybody who has read the Revised Report on Algol 68
knows that the language as defined there consists of the
set of production trees of the grammar of the language.

Each production tree needs to be represented in a
representation language, which is the form we usually
seen when we think about programming languages.
However, back then machines had such wildly differing
wordsizes and character sets that this distinction was
necessary. After publication of the Revised Report, with its
included representation meant publication of programs,
but not for actual implementation on hardware, they
developed a `standard' hardware representation.
Even in that representation there were multiple representations
of the keywords in the language, e.g.

.WHILE

and

WHILE

were allowed representations for the exact same keyword.

Implementors were strongly suggested to use the standard hardware representation, but if documented, they were fully
free to chose whichever representation they like. Hence, an
implementation may perfectly well use

ZOLANG

instead of

WHILE

as long as it is clearly documented.
