Some games do this by splitting off the highest resolution textures into a free "DLC" that the user can opt not to install if they want to save space. It's sometimes done for audio as well, e.g. optional Japanese voices for the English release of a JRPG.

Remedy's Quantum Break had an unusual spin on letting users choose the install size, it made heavy use of live action FMVs which could either be downloaded ahead of time or streamed on the fly as they played. Downloading the FMVs more than doubled the games footprint.

good idea : one why chitty etxture quality, one with average, one with quality texture. They have done this on web-videos. Why not on video games files ?
