Could also dip into Tempest Cleric for a few levels. Get Heavy Armour/Martial Weapons and a 2d8 reaction damage if hit in melee at first level, and at second level Destructive Wrath, a channel divinity ability that allows a lightning/thunder spell to inflict max damage. Plus extra non-sorcerer utility spells, of course, but you probably won't have stellar wisdom without an appropriate buffing magic item.
Thematically good as well.
Thanks for that idea.. just tried it .. and i like it ... although I guess it wont beat my EA fire wild magic sorcerer run from a damage dealing perspective
