How can I accomplish this? The lowest I have been able to set the clock is 16MHz by modifying the boards.txt file and setting genericSTM32F103R.menu.cpu_speed.speed_48mhz.build.f_cpu=16000000L.

For LibMaple core, I guess you have to implement it manually and add extra entry in the menu.

You can run a Google "site-centric" search on the old forum, like:

But, the biggest concern was to not break USB.
