The idea seems sound but there could be bugs. For example, does dividing up memory using fake NUMA over time lead to not being able to allocate needed DMA buffers? Probably not, but there are many things to test.I haven't seen anyone report problems with the NUMA changes. Is it perhaps time to release an official kernel? Image may be NSFW.
Clik here to view.
As far as I can tell, the main reason Intel went with overclock settings by default on their 13th and 14th generation CPUs is because journalists generally test with default settings and faster is better publicity. The instabilities resulting from electromigration were not such good publicity.

As the time of journalists testing the Pi 4 and 5 with default settings is long past, I think it's better to focus on stability and be conservative with changes to the Linux kernel. At the same time, since fake NUMA does not involve any voltage or clocking changes, damage to the Pi is unlikely.
