Wouldn't this just be this (untested, not right for keywords, quasiquote):
#lang racket
(provide (except-out (all-from-out racket) quote #%datum)
(rename-out [-#%datum #%datum] [-quote quote]))
(define-syntax-rule (-#%datum arg) (-quote arg))
(define-syntax (-quote arg)
(syntax-case arg ()
[(_ i)
(and (number? i) (not (inexact? i)))
#'(exact->inexact (quote i))]
[(_ i) (quote i)]))
Or maybe just a reader change to read all numbers as inexact?
