I've started maintaining my own build version of Sins Plus for Entrenchment for use in combination with some of my other mods. There was constant demand for merged mods so I thought it was the best course. I maintain a stand alone version as well. You can find it in my mod thread here:

It's called GalaxyMod. It is basically Sins Plus minus the Ship Graveyards and perhaps one or two other little things that were problematic in Sins Plus.
The current release will work in Entrenchment 1.03 but I have discovered some 1.03 specific issues that should be corrected. I've already done so privately and will have to release a new version shortly. I'm just hoping to test a bit to be sure I haven't mucked anything up while updating.
