Level 70 Craft-able weapons should have a +1 option

[Kaiche]

Hello! After crafting a few of the level 70 weapons (such as the Sarnga/Astrolabe) I've began to love the design and freedom you can get with these weapons and the customisation of materia you can put in to your liking.

After getting my relic those weapons are pretty much obsolete now and server no purpose anymore. I think that these weapons should have a option so that they can be upgraded to +1 just like the relics but still being able to be melded like before and still require the same amount of mist from the shop in Revanant's Toll.

Please let me know if you think this is a good idea

Edit: Since a normal relic is level 80 the relic precursor +1 could be ilvl80 with the choice of melds.
