PoV + Boon Duration
I’ve been running this build since the day they buffed rune of the pack. The difference is I now use berserker’s trinkets instead of knight’s. I am happy with my build, so I wouldn’t say your plan is not viable.
I also considered +20% boon duration food, but then -40% condition duration is just too hard to ignore in WvW.
For your question, unfortunately, I have never paid attention to it so I can’t answer it. Maybe I could test it later today after work.

Why bother being a Guardian if you don’t guard anyone?
Are the boons gained when you convert a condition with PoV affected by boon duration?
Yes, they are. I just tested it some moments ago in HotM with 6 in Virtues and Water runes (+50% total) with one of the NPC (thief is pretty good for testing since the NPC will most likely use her blinding powder for a single condition at a time), and then again without any additional boon duration. The boon duration from conversion is noticeably longer with the first setup (fury > 12 seconds with boon duration and only a bit more than 8 seconds without +duration). Same applies to Contemplation of Purity, btw.
A landing you can walk away from just wasn’t fast enough.
Note that if the shout you use innately gives you the boon that you would recieve from converting the condition, the shout only removes the said condition. For example, using Retreat to convert Burning, Cripple and Immobilize will remove the condition(s) but will not prolong the durations of Swiftness or Aegis granted when using the shout. If you want to have longer durations of the boons you convert from conditions, try to use shouts that do not grant the conversion boons already.
