I tested building and running the RISCV base and RISCV NPB disk images. I found that the building process was somewhat flaky, but was ultimately able to get it to work.
Previously, the RISCV kernel extraction failed on a machine with Docker version 27.5.0, but succeeded on machines with Docker version 27.3.1. However, upon re-testing, the kernel extraction succeeded on Docker version 27.5.0. I also found that the build process for the disk images would sometimes time out, likely due to timing issues.
After building the disk images, I ran simulations for booting the base disk image and running UA size S on the NPB disk image. Both ran as expected.

Need to add documentation in README.md or BUILDING.md about how users can/might need to adjust the wait times to avoid timing issues when building the disk image on their own systems. It would also be nice to have a comment in the Packer file.
