I know this is going to upset a lot of people ...
Neither Constantine nor Eusabius are saints in the OO Church. Both are heretics; the former was baptized by an Arian, the latter insisted on following Arianism. This is well documented.
Unfortunately, Constantine crept into the hymns of the Coptic Church recently in the 20th century. There is no evidence whatsoever, prior to this period, that he was a celebrated saint in the Church.
I agree with you on this. I would be very interested in any evidence you have for the late additions to the psalmody, synaxarium, etc.
