Trog --
If you jump over to the Coda Utopia Planitia site, you'll find a bunch of threads dealing with ships out of the SRMs. You may have to dig a little bit (there are a few pages of threads), but there are many different takes on the various TNG-era ships.
I, personally, have converted all of the Spacedock Starfleet SRM ships that weren't covered in the NG. You can find most of them in the "Starfleet, 23xx-23xx" threads. I included my Miranda and Excelsior writeups in a "23rd Century Starfleet" thread (most of the ships in that thread are from the FASA SRM).
