I don't think so. Here are the FAQ about the blue card: http://www.bamf.de/EN/Infothek/FragenAntworten/BlaueKarteEU/...

Quote: "What preconditions need to be met in order for an EU Blue Card to be issued? 1. Applicants must provide proof of a completed university degree. If the university degree was not awarded in Germany, it must either be recognised or comparable to a German university degree. 2. Applicants must either provide proof of a concrete employment offer or present an employment contract that has been signed or that already exists. 3. This offer or contract must be based on a minimum gross annual salary."
