Not even possible. That's just not how TRANSLATE works.

TRANSLATE maps individual characters to other single characters. If
you map, say 'xyz' to '123', then EVERY instance of 'x' in the string
to be translated becomes '1'. Every instance of 'y' becomes '2'.
More than one of these transformations can have the same destination
character. So 'xyz' can be mapped to '113' if you want. This will
turn every instance of 'x' into '1' and also every instance of 'y'
into '1'.

For example, the expression

translate('Hello, world!', '123', 'olH')

has the following components:

String to be translated: 'Hello, world!'
Map from: 'olH'
Map to: '123'
Resulting string: '3e221, w1r2d!'

This is nothing like what you're trying to do.
