Maybe. Another thing you can do is use a Variant Human Arcana Domain Cleric. Use your feat to take Magic Initiate: Druid with Shillelagh as one of the cantrips (your choice for the other cantrip and 1st level spell). Take Booming Blade/Green Flame blade as your wizard cantrips from the Arcana Domain.
You don't get the extra +2d8 from the Tempest domain, but the Arcana domain lets you add your Wisdom modifier to damage with any Cleric cantrip at lvl 8 - which Booming Blade counts as for you, due to the 1st level domain feature.
So you get to use your Wisdom as the Attack and Damage stat with your 1d8 club or staff (and you don't need to pump a secondary stat), and you get to add your Wisdom modifier to damage a second time from the 8th level domain feature. At lvl 17 (assuming a 20 wis and a +2 staff, because why not) you have: +13 attack, 1d8+12+3d8 thunder damage, +4d8 if they move. And at lvl 17 it's quite likely to have found a +2 wis tome (another +1 att/+2 dam) or even a powerful magical staff (Staff of Thunder and Lightning, Staff of Power, etc.)
It's at least equivalent to the tempest version at lower levels due to double dipping on the Wis stat.
