Since you already have a great thunder mitigator I'd recommend using your UOC on some op unit like Allanon, Haile or something like that. (I think there's a video by Ushi on YT for that) As for the fire mitigator, you'd better wait for Darvanshels 7* and summon for him then IF you're desperate to clear that FG since you already have a lot of good mitigators including Gazia, who is a free unit. Hope I could help.

PS: I could put my Adel as my friend lead for a while and you can try clearing the FG with him if you'd like.
