In addition to that, I still believe More Like This is a better option for you. The reason is that the MLT is able to evaluate the interesting terms from your document (title is the only field of interest for you), and boost them accordingly.
Related your "80% of similarity", this is more tricky. You can potentially calculate the score of the identical document and then render the score of the similar ones normalised based on that. Normally it's useless to show the score value per se, but in the case of MLT it actually make sense to give a percentage score result. Indeed it could be a good addition to the MLT.
