Would something like
(require syntax/parse/define (for-syntax racket/base racket/syntax))
(begin-for-syntax
(define-syntax-class path
[pattern path:id #:with prefix (format-id #'path "~a:" #'path)]))
(define-simple-macro (new-require path:path ...)
(require (prefix-in path.prefix path.path) ...))
Work for you?
