Have you tried taking a look at the How to Make a Xeno Species article? It could be a big help in the creative process. As far as the reptilian idea, it is not bad, but it it has been done before in both canon and on this site. If you plan to go reptilian, then you will have to find a way to make them unique. A good idea might be to use characteristics of different animals.
