We played with something just like this last year (called projfinder): http://projfinder.com/
That is just a simple demo application that was a proof of concept. Center the map where you think your data is from, enter in a sample X,Y from your dataset and it tries to guess what projection your data is in. Nothing fancy like parsing arbitrary file formats etc… just simple X,Y from your data. I gave a presentation on it at FOSS4G-NA 2013 (you can reference it here): http://reprojected.com/blog/2013/05/28/foss4g-na-2013-was-a-home-run/ If you are interested in the code I can point you to it. In the end it is basically a simple web-service built around a PostGIS SQL query that does the distance calculations to percolate up likely projections against the EPSG database.
