That could have potential today, like on the Orion!

They were standard 18mm x 70mm and only available as D8-0 and D8-3, both almost filled to the top. They were really just HOT C engines with 12.5 N-sec spec and about 11 N-sec tested. They did have a core to get the peak thrust up to about 16-18 N but the average thrust was closer to 7 N rather than 8 N.
