I'm not sure what the usefulness of this is - you're effectively
encouraging people to build modules with a different configuration
from the main kernel, which is bad news.  Since it's the configuration
which dictates whether the kernel (and modules) are built as ARM or
as Thumb2, you'd have to use two different configurations, one for the
main kernel and one for the modules.

That's really something we should not be encouraging.
