Very interesting points you have here, CamDawg! Hope that Andyr will soon be back working on the next version as the need of UBv16 is getting higher and higher!
Something else worth investigating are Becky & Diane (becky.cre and diane.cre). Becky is a girl who wishes to abandon her old mother (Diane) and go adventuring. They seem like they could be inserted more or less anywhere. Both need alignments assigned and both use 'diane' as their DV, but otherwise seem ready to go.
From devSin over in the Fixpack forum. amntrap1.bcs summons the NORH knights to attack low-rep parties. There are, however, two more scripts that do the same (amntrap2 and amntrap3) that are currently unused. There's also an unused tax collector.
Dunno if UB already restores these or not, but thought I'd let you know.
