Dear Sstikstof
As-salamu alaykum
The tradition to signify a call to prayer to invite believers to worship would have started from the Prophetic ministry and would thus arguably be an en masse practice.
An expectation is clearly captured in verse 62:9 and there would be a strong argument here to suggest that a practice had been initiated by the first believers before ritual prayers / congregational worship.
Whether one call is made or a secondary call (iqama / iqamat) is made just before prayer starts does not conflict with the essence of the Quran's guidance on this matter which is the need to establish worship and the expectation that there is a call of some form.
Therefore in my humble view, this would have been an en masse practice enshrined later in the Ahadith corpus. Hence, I would see no need to break tradition.
Calling to prayer is not a new concept amongst Abrahamic faiths (no matter how it is performed). One is familiar with the Jewish Barechu or the Christian Bells.
The Quran in the main does not appear to be focused on how it is performed as long as some suitable form exists.
I hope this helps, God willing
