Agreed that finding all connections would be a big project, but I think that anyone who tries to build off your work will either have to do the literature search anyway (at least for the parts they want to work on), or will end up reinventing the wheel. Perhaps you could find one or two literature review papers for each topic and cite those? I would imagine that you could get most of the value by finding ~20 such papers, which while not an easy task for fields you aren’t familiar with, should still be doable with tens of hours of effort, and hopefully those papers would be useful for your own thinking.
