I don't think it's in our own advantage to create a pile of new questions with slightly different approaches for a similar feature. Maybe it's a good idea to keep it at a single request and chime in with additions, approaches etc. Now this request has 7 votes and a similar request has 15 votes. Maybe one request with additions could already be approaching 20 votes.
Next to that, when a feature request eventually has a high positive score, it's much easier for the developers to see all additional wishes, ideas and suggestions in a single question and answers stream, instead of several questions across the database.
