Yes, for a solo 7075T6 is plenty strong enough. The tandem one is steel, but the Boost conversion on my 464 is 7075T6
Plenty of boutique road rear hubs use 15mm 7075T6 axles, and converting a 15mm through bolt front hub you already have the bearing support tube doing the heavy lifting. I'd be pretty confident in a 6082T6 adapter made to that drawing, the 464 one is a different design with thinner walls.
