Tertullian.org
Besides having on-line original Latin and English translations more recent that the ANCF versions, this web site also has collections of Church Fathers that were translated in the 19th Century but that didn't make it into the 38 volume Church Fathers we all know and love.
Since they are already in text (or html) and not just page scans, it would seem that making Logos editions should be easy. I am working on one of them as a PB, but don't ask for it here. I will not give away a more recent translation on Logos's servers than Logos sells.
