Mythic Suggestion

I have an interesting suggestion with the coming of GEO and RUN mythic. Why not make it possible to make mythic changeable mid-quest? Currently if you change mythic during the quest it forces you to reset everything. I'm about half way through mythic now and have traded everything in to save space, minus the Alex I have on hand and the Nyzul book which I'm 10k points short of. I really don't want to lose the gil I've invested into it because I want to change the weapon, nor anything else for that matter. It may not be possible to change this but it's an interesting thought considering the incoming additions to mythic. Perhaps it could be a one time thing or through some related quest.

I was holding off because I didn't know what they were doing for Run and Geo, but it looks like they will have a separate quest line. So no need to switch.

That's interesting. It wasn't really GEO or RUN I was after. It's a long shot since they didn't do it when they added SCH and DNC. I am working on NIN but I really want to switch to BST. I don't want to lose out on 150m-ish gil, though.
