Could you use a PolyForm license instead? They have a set of standardized, source-available licenses that are much shorter and easier to understand.
"The PolyForm Project is a group of experienced licensing lawyers and technologists developing simple, standardized, plain-language software source code licenses. PolyForm aims to fill gaps in the menu of standardized software licenses, like non-commercial, trial, and small-business-only terms."
