Can you share more about why it's hard to submit the preprint for review unless its first published somewhere? Wouldn't you be able to submit the preprint directly to whichever conference or journal you want it published in? For a different way to receive feedback for a preprint consider [url-redacted]. I created it partly out of frustration for the time it takes to publish smaller work. Although not currently implemented, I can provide a version that keeps review comments private.
