Well, if my husband carries through on his promise, the voicing concern should be addressed (to some extent - there are a lot of sound files to go through!) for 4, as well as the Imoen issue. (And all other issues raised on the v3 and above bugs thread.)
I remember when I was first beta testing, the talks where Imoen's referred to as your sister definitely came after Spellhold. At some point during the beta processing, the timers were adjusted to speed up the love talks a bit, and that's what caused the issue.
So, 4 will be worth playing, and will likely happen next month. 5 probably won't happen until the fall, but should be worth the wait.
Cal, did you uninstall Angelo with him in the middle of your stack? Sometimes that doesn't always work out all that well. I've uninstalled the second mod in my stack with no issue, and then gone on to have heaps of problems uninstalling something second or third from the bottom. For that reason alone, I always build a fresh install, unless I am uninstalling the very last mod. Some also have good results uninstalling everything in reverse order until they get to the mod they want out, then reinstalling the mods they still want in the same order they were originally in.
