Dev made the original Zenith too easy to obtain and regretted it - everyone can get it easily and therefore it had no special value to it.
It is why they added in the grind and decided to increase Allagan weapon stats to make it better than Zenith because it was just too easy to get.

Saying NO to your proposal - as it is more like just handing the relic to you and very well end up like Zenith where it really means nothing to own a legendary zodiac weapon.
