A more usual way to drive the diff machinery and react to its findings is to use DIFF_FORMAT_CALLBACK interface, and walk the collected diff_queue to work on the paths discovered. The way wt-status.c builds "Changes to be committed" list out of the "diff-index --cached" it internally runs and "Changes not staged for commit" out of the "diff-files" it internally runs would be a good example to study.
