it's certainly plausible, but probably not what you'd expect to hear from a barovian as an outsider PC - especially not one above 12 OCR. the current way the dialogue is set up & phrased is that entrusting
you (a 'pitic', 'fey' or whatever else) with his valuable deliveries is completely out of the question. the same goes for offering you permanent employment.
it's a subjective argument, but i can't see him apologising or entertaining the future prospect of work besides the item supply stuff. it's also a bit misleading, considering how exceedingly rare it is for your OCR reputation to be changed. aside from buying influence gear, the only people lowering their OCR are going to be charisma based classes, which usually dont have problems with OCR to begin with.
You're unaware that the 12+ OCR or whatever the breakpoint is only affects the delivery quests. Up to 15 he will still offer the crafted item turn-in work.
Mooner was simply suggesting that the dialogue might be better fitting if your PC pushes for work, so he then offers that.
yes, pretty much. upon asking for work, he'll initially just outright refuse - and there'll be a dialogue option to plead or reaffirm that you really need work. in which case, he will begrudgingly offer to pay for the crafted items as usual. maybe this would make navigating through his dialogue a bit too lengthy though, especially if it has to be done each time
