I am actually in for a Story Mode coil that is in conjunction with the actual version of the same tier of coil.

Especially in 2.4

I am pretty sure that for story/lore wise, we will transit to the expansion after 2.5 so both the main story and the coil story will certainly meant something.

I can beat the third coil within 2.4 itself like how I beat second coil within patch 2.2, but that doesn't mean that others may be able to beat it in "catch up patch" aka 2.3/2.5. Need not to say, once we transit to 3.0, 99% of the players wouldn't really give a shit to 3rd coil even if you put it in PF with echo because people will be all busy with the new content in expansion pack.

I don't think it is that difficult. I don't think coil story should be restricted to the so called "elite raiders". We have story mode for all the primals for every single player to enjoy the story, I don't see the reason why everyone isn't allowed to enjoy the coil story either. There is no harm in letting everyone, at least to enjoy the Final Fantasy story.
