No, the double-quoted ''sub doesn't work (triggers bad-syntax error).
Nor does this (with quotes added to `sub-id` within the `require` and
`provide` forms):
(define-syntax my-module-begin
(lambda (stx)
(syntax-case stx ()
[(_ body ...)
(with-syntax ([sub-id (datum->syntax stx 'sub)])
#'(#%module-begin
(module sub-id racket/base
(define x 2)
(provide x))
(require 'sub-id)
(provide (all-from-out 'sub-id))
body ...))])))
