The DSRV is broken in the engine, so that can't be touched, by modders anyway.
The doctrine system is made of peaks and valleys... I wish there was a neat way to express to everyone what is and isn't capable, but frankly it would just be a list of random things, not really making much sense. And what makes it even crazier, is that the level of control varies by platform type.
I'll look at as much as I can... starting with the things that Thomas did in SCXIIc, since I've got a pretty good grasp on what can be carried over successfully.
Unfortunately, the inherent behavior of just about everything appears to have worked (from what I have heard) much better in SC than in DW, so there's so much more that needs to be fixed.
Cheers,
David
