A lot of the reason champions get updates for visuals is because the older champions fall so far behind that they 'don't fit in'. Pizza feet, for example. I'd say at this point that the fact that lots of champions have less than 40 words of VO full stop, is at that point, and that there should be a team to add a few lines to all these old champs. A dedicated team that at least works towards the 'goal' of expanding the VO would be lovely.
Alternatively I would be happy if they had an animation-update team that added new animations to champs who have already have a model thats up to date,but lacks animations(like shen,singed,alistar who all received a VUs,but didn't receive too many animations)
Miss Fortune is such an interesting deep character in lore....the quotes in-game dont really reflect that at all.
Despite his faction not being fully updated yet (Ionia to be specific), Shens story is, and there is a lot of potential for new quotes for this dude, mainly due to all the champions he could interact with (not to mention some neutral monsters).
Have potential for new interesting quotes, mostly for interactions sake.
I expect its a bit harder to give these champs new quotes, mainly due to their factions or even their lore not being updated as well.
Succesfully updated voice overs (various degrees): 
(all pretty much during the larger lore updates)
Agreed. Some all champions have such few lines that it's sad...
That being said, when Riot VU's the champion, they usually change their lore and general concept a little as well, so they might not be willing to invest time in recording VO that might become obsolete in the future.
Ok
Yeah, but how are you going to get the rito buck$ to replace the VO? NA voice actor land definitely costs rent.
So, are you saying that Riot should pay writers and voice actors just to add few lines of dialogue to champions that could be updated in the future?
Sorry, but I don't agree with you. I'd rather have them spend those resources on another team that does full VGU.
