well, first of all... your acc is great at it is.. imo
focusing wind sounds ideal for you ofc.. even if you just have the 1 ssr of that element it's good enough, since you have Sol who works perfectly on any team, it's a nice combo.
BUT if you're motivated to re-roll, you could just do it on the side, since you're not too far into the game it wouldn't be a total waste of time to restart. haha im contradicting myself
don't move right onto events, just focus on raids, preferably wind (standard wind has higher chance to drop weapons than expert) and try and get some wind bows and mlb them..

the 2 ssr eido you have are both... useless at that stage anyway, the only thing they can be good for is getting you more gems from others using them or the summon ability.
elemental eidolons are pretty crappy compared to character attack eidolons when you're that early into the game and haven't developed a proper grid.. but you can slowly do that into the future as you get more weapons.
also.. nice, thunder/dark/fire/water JUST what you needed XD

and.. picking D'art isn't a bad choice, her def/atk def debuff is needed, though try to get cassiopeia and gawain next (for healing/def buff and ambush) cause as perfect as Sol is, healing/cleanse, chaos magic and atk debuff.. it's never bad to have more healer XD
D'art is actually the perfect soul for raids, as you can use her snatch ability to have more chance to find weapon drops in them.
don't buy the SSR guaranteed ticket until you know you're happy with the account, and as you wrote this thread.. well it answer itself.

sorry if my advice isn't so good... i'm not very good
