let alone and letting alone

[Boris Tatarenko]

I'm wondering whether it's OK to use "letting alone" instead of "let alone" in the following sentence and in similar sentences.

1) He doesn't like me, let alone you.

2) He doesn't like me, letting alone you.

It doesn't work in BrE. The stock phrase is "let alone".

Likewise American English.
