I'm not going to change onlyupper and onlylower, because that could break scripts, and it would make them less efficient than they need to be for normal use. But you can get what you want using the aggreate function with some lambda functions. These check only the first character in a piece label. Just create your own stalemated subroutine that uses them.
Instead of onlyupper, use "aggregate lambda (#0 onlyif isupper char #0 0) pieces"
Instead of onlylower, use "aggregate lambda (#0 onlyif islower char #0 0) pieces"
