How to allocate kyros in my position?

Looking for some suggestions, and given some of the posts lately, coming here to ask instead of reddit (looking a bit mean right now, though this forum has gotten a little rougher lately, as well). 

Kyros are such a crunch.  I've got other things to farm, I cannot devote so much energy to these, which makes it a very slow process to bring G12 to relic.  And I have a LOT of toons at G12, many of which are mostly waiting on kyros. 

I'm going for JML right now, and in relatively good shape.  But the kyros will timegate the whole process.  If it weren't for those, I'd be looking at having JML about the end of the year.  But instead, it could be more months.  

I'm also doing side farms.  I know I should probably stick to my main farm, but it's so long anyway.  Giving that one piece to Old Ben still leaves me with four more toons who will need those for a G12 piece.  And OB won't really help my teams at relics, so much.  He's not that great, and I have GK with my JKL right now.

I have Iden and Merrin who could both level up a full gear level with the kyros I have right now.  Both are at 6 star, but I'm farming shards almost daily for both, so with both of them around 50/100, should only be a couple more weeks before I have them at 7 star (did you know that wrapping text in asterisks here turns the text to italic?).  Iden I use in GAC, and I'm slowly farming Defender (currently at 4*).  Merrin seems like a great addition to Nightsisters, which I recently brought to G12, and am finding to be more powerful on offense than I would have guessed.  Plus, I am sort of slow farming for Jedi Cal now that I have JKL. 

I really want to give it to Merrin, as you don't have access to her best special until G12.  Iden has an omi already, and does okay.  Merrin, I may give an omi.  

I'm sort of looking at being promoted to Bronzium from Carbonite (if my ranking holds well enough, or improves - it's already outside the typical Carbonite range).  That means more teams.  Having a solid NS team for offense would be nice.  Iden would get a boost, but how much?  I'm asking... if Iden already has her omi, do the gear levels make a huge difference for this team?  Is NS going to benefit more (I'm putting Merrin in for Talia, so it's a huge difference).

Long post, I just can't decide what to do.  I wish kyros were easier to come by (or really that so many weren't required... just for current farms, I need nearly 1000 between the two types).

I could link my swgoh, but I think I've described enough.  There are so many other toons that could use kyros too, but I think these are my priorities right now.

So, do they go to a G12 JML req, Iden, or Merrin?
