I have found a transparent dialer that works with sapphire 2.0. I didn't know if this was old news or not, but it was from a post by gflam from the droid themes forum, link is below. I have only tried the smoked glass dialer in his post (installed through recovery) and it works for me. Please MAKE A NANDROID BACKUP before trying any of these. Also I believe ecsnead69 has a dialer too. Skull Candy Theme And More!
