One question: is there text in conversations in Skyrim? I haven't seen it, is it an option you can turn on somewhere?
Yes, you can turn on dialogue subtitles, I believe that's in the Settings > Gameplay menu screen within the game. Edit: You may need to scroll down the list of settings to see the option.
I'm going to try decoupling the esp from Oblivion.esm and then monkeying around with SkyrimEdit and see what I can do.
Note that the main scripting language has apparently changed extensively in Skyrim compared to past Bethesda games--really it's a new language with new structures and such, called Papyrus--so I would not expect that you'd be able to convert the old .esp files easily. Scripts will likely need to be updated, although exactly how different it all is won't be clear until the CK is released (in part because it seems like the old scripting language may be present as well, but it is unknown to what degree it's still functional vs. vestigial). On the other hand, the good news is that there is at least some basic companion functionality already scripted into the game (open your inventory/wait here/go home), which can be obtained just by putting an NPC in a certain faction.
