How would this interact with or complement __read_mostly?

Currently, the mechanism we are working on developing is
independent of __read_mostly. This is something we can look more into
while working further on the mechanism.

Please either integrate the two or explain how they differ.
It appears that you haven't considered how you might exploit
or expand the existing mechanism.

I think __read_mostly is about grouping stuff together that's rarely going to
be read to make the CPU's data cache more efficient.  It doesn't stop people
writing to such a variable.
