It should be possible, in any language of Wikisource, to check all existing text against
What do you define as existing text? Only the text currently stored in wiki pages? Also the text layer of the DjVu or PDF files in use on the wiki? Also the files uploaded but not used yet?
a known dictionary valid for that year, and to find words that are outside the dictionary. These words could be proofread in some tool similar to a CAPTCHA. They might be uncommon place names that are correctly OCRed but not in the dictionary, or they could be OCR errors, or both.
Has anybody tried this?

Such finds are not necessarily the only OCR errors. Some OCR errors result in correctly spelled words, that are found in the dictionary, e.g. burn -> bum. So full manual proofreading and validation will still be needed. But a statistics based approach could fill gaps and quickly improve full text searchability.
True. Listing tasks to direct people to is also always a good thing on wikis, better than leaving people spend time on finding what to do.
