Without HTTP, it'll be a little clumsy. The downloader won't be able to pause and resume the download, and won't know what is the progress of the download (unless you tell her the exact file size beforehand, which might be tricky sometimes, especially in automated circumstances). You will also need to resort to this for sharing the metadata such as the MIME type of the file. I think using HTTP for this is more robust, even if it requires you to download and spin up OnionShare. Btw, the fascist firewall evasion is great. In my dorm, the only allowed ports were 80 and 443, and I was able to connect to Tor effortlessly.
