I ran it with 5-7 two years ago.
Fullback dive, halfback sweep, quarterback bootleg.
We always faced defenses with one high.
I defined the box as everyone but the two defenders closest to the sideline on each side, and the safety.
We always went two tight.
Front seven always got the six in the box. I gave them their assignments after they lined up, since we could have coaches on the field. I used my practice time on O-Line fundamentals rather than scheme.
On the dive, the FB popped through as quickly as possible. It wasn't a power play. We got a ton of long runs off it. Drilled the hand-off like crazy using the QB tee.
On the HB sweep, the lead halfback took the Wide 9 (DE/LB). FB basically skip pulled to replace him and then got the corner. QB had the backside Wide 9.
On the bootleg, QB used a reverse pivot to let the blockers get out ahead of him, but still got going very quickly. Lead HB went Wide 9, trailing HB went CB, and the FB shot through like it was a dive, but with no ball fake.
At least that's what I think I did. I might have done it slightly differently, and the above is what I would have used if I'd had that group the following year. Hard to remember at this point.
All worked great.
Only block you have to hold very long is the playside TE when you go outside,
