Subtle Meta gets rid of V+S. Dark Crystal or Hat or Ruby , in Xanathar's p136+ , are 100gp arcane focusi (as in it could be anything really) = Ta Da , Natural Spell equivalent at level 5. Should also work with Holly berries (etc) for the Druid. Make the item during downtime just before sorc 3. Maybe a custom cheapy magic item combines together druid focus and sorc+ focus.
Sorc 1 / Druid 2 / Sorc 2+ , coasts on moon power at ecl 4 , good after
Sorc 1 / Druid 3 / Sorc 2+ , "feels" better than above , worst level falls on Cantrip boost
Sorc 1 / Druid 5 / Sorc 2+ , a weaker combo , soft until Sorc 5
Sorc 1 / Druid 3 / Sorc to 3 / Druid +X , more druidy , sorc 2 gets the meta points over for wildshape
War Caster feat first , then whichever Caster stat +2 and +2.

Should stop thinking out loud with typer-writer and similar distractions (etc excuses and)
Disguise meta gets rid of V + S , and one of the 100gp magic items is an alt Arcane focus (doesn't have to be specifically a Hat).
So would this be a weird backhanded and not particularly strong way , of doing a 3.5e Natural Spell equivalent ?
Or is the Druid no casting in Wildshape clause inviolate (until level 18 of course) ?
edit --- OR is it just this Sorc that's able to cast in Wildshape ?
