Yes, I would like to do that as well (and tried), but there are symbols
set in am335x_evm_defconfig that are not set in am335x_hs_evm_defconfig
for example. If I remove that symbol like this:

  # CONFIG_... is not set

'make am335x_hs_evm_defconfig' will complain:

  generated_defconfig:87:warning: override: reassigning to symbol CONFIG_...

I don't know how to get rid of that warning without the additional files
I introduced.

Best
