Did a little theorycrafting on weird multiclasses, and oddly enough, an "Eldritch Knight Fighter 6 / Tempest Cleric X" dual class works really well even though they have no stat overlap.
It's just dependant on you taking things that don't require any INT in your Fighter spell picks. Shield, Magic Missile, and Expeditious Retreat are good and don't rely on your Fighter casting stat, which frees you to focus on WIS for the cleric stuff.
Plus, you're not losing out on any feats, you'll get a ton of spell slots in the end, and you get the huge AC boost of Shield while still getting multiple weapon attacks per turn that you can do while concentrating on any of Cleric's coolest spells.

The one disadvantage that I can tell is that you're basically just an Eldritch Knight until level 7, so the class fantasy kind of suffers for a fair period of time. I'd definitely be reflavoring the arcane abilities that I was getting from Fighter as being divine in nature.
