Maybe enabled with a > --ignore-duplicate-include option. I'm reluctant to add a command-line option for something that can be so easily coded in native m4. On the other hand, m4 2.0 will allow loadable modules thanks to libtool, so you could write a C module that redefines include to have your desired semantics, and load that on top of the normal modules to change include at the C level rather than the m4 level. - -- Don't work too hard, make some time for fun as well!
