My main problem is this: RT and DH don't really play cleanly together, no matter how much any of us want it to. I've been staring at both books and the list of party members likely to volunteer for (or murder their way to) it...
I've already chain-sawed the rules by allowing the party's seneschal to become an Interrogator due to storyline reasons -- their Inquisitor was assassinated, no one else really wanted (or was suited, personality-wise, or attended consistently enough. So far it hasn't been pretty, but I'm working on coming up with rules for splashing RT characters to Interrogator/Inquisitor that are less suck-tastic than my quick-fix kludge I threw out there to test/use ...
I've always been more comfortable with the Inquisition side of the house, but with my plan to introduce a Warrant of Trade, I'm somewhat at a loss for crossing DH/Ascension characters into a Rogue Trader. No doubt, I'll figure something out before then, but I am very interested in any comments/advice you guys might have that could cut down on my development time... So far, out of all the characters, the party's psyker seems the most likely to be the recipient, as most of the other players don't want to be in a leadership position, or they don't make it to the games regularly enough to throw that kind of load on them.
So, anything helpful on non-suck ways to take a rank 8 pyromancer and splash her to Rogue Trader?
