I dont think it makes no sense to check spf at submission ( unless exotic reasons ), dkim could be "sign only" with submission , ok as DMARC depends on results of SPF and DKIM milter before it gets more difficult, but might configured with milters options, like ignore.. etc, the most clean way might be having second instances of the milters and other configs depending to smtpd and/or submission.
