I don't have experience with models, but if there is a compatible free software model (E6ing is FOSS, though not GPL) which suggests tags with a reasonable degree of accuracy, sure. Given the way images are uploaded, if such a model suggested existing tags for all new submissions the uploader could validate, that'd likely be a great jumping off point instead of only a handful of tags and a +tagme. Maybe these suggestions could also exist within the tag editing page for others to validate in the future as well.
