What could a space telescope just for solar system science do?

Sep 23, 2020
The National Reconnaissance Office (NRO) donated two space telescope to NASA in 2012. One is being refurbished and re-engineered into the Nancy Roman Telescope. AFAIK there are no plans for the second piece of hardware. NASA sponsored a workshop for planning for a use for it (https://science.nasa.gov/salso/post-workshop-updates/), but there has been no updates since 2013.

Perhaps NASA install a NIR/visible/NUV camera and a spectrograph on it, and launch it on a Falcon 9 or Falcon Heavy for a solar system telescope?
