Brace expansion is done before quote removal, as you can easily see:

unicorn:~$ echo {"a".."d"}
{a..d}

You're simply trying to make things too complicated.  Bash doesn't
support this style, and even if it did, you're only using braces to
generate a list of 6 words which are one character each.  You could
simply type them out:

@ A B C D E

Isn't that a lot nicer than {$'\100'..$'\105'} ?
