At risk of repeating myself, you should be aware that this decision will not respect the will of the senders or recipients, but the probably well-intentioned but not necessarily well-informed will of the sending mail system operator.
You *will* cause unintended mail rejections, and the parties affected (sender and recipient) are the ones who are least able to change anything about it (except changing their mail service provider, giving up on mail consolidation by forwarding, or migrating to a mailing list manager that does DMARC mitigations, all of which incur considerable effort and disruptions). One option that you should consider to mitigate the effects for recipients is to allow per-recipient DMARC exceptions, because the recipient is the one who ultimately decides whether mail is wanted or unwanted. If you tag messages for a transition period of a month or so while already providing such an exception setting, recipients will be able to adjust their settings before mail gets lost.
