I realize Click2Flash was discontinued over "Apple changes" but the release notes in 10.12.2 clearly state that Apple has re-added sideloading of Safari Extensions:
"Fixes an issue that prevented installation of Safari Extensions downloaded outside the Safari Extensions Gallery"
Would this resolve the blocking issue for Click2Flash?
