This is not biblical or church teachings, but I would suppose that if Mary had said ‘no’, then she may not have included in Scripture.
We don’t know; all we know is that she said ‘yes’ and we are where we are because of that acceptance.
Then for all we know Mary could have been God's 15th choice to bear His Son? :)

Not really, since there never would have been any scripture if God had chosen to give up upon being told "No". IOW, if God would have simply moved on to ask the next young girl, then SOMEONE would have eventually said "yes". Even under your supposition, we are where we are ONLY because God refused to give up. So, Mary would only be worthy of your veneration IF God had decided it would be Mary or there would be no Christianity, AND that Mary was free to decline. Thankfully, God's love for His elect proved much stronger than taking a chance like that.
