I think there might be a slight difference between "I want to do PvP" and "I want to do PvP PP". For the former, I think it's not too unreasonable to expect PvPers to jump through the same or similar hoops as other player groups have to, seeing that there's probably not going to be any change in match making and getting players together "organically" any time soon.
For the latter I agree it might be a tad more difficult.
Just speaking for myself, but I try not to shoot down reasonable suggestions. I am averse to PvP gating PP though, which is one of the more common suggestions, bordering demands, made here.
I have signatures turned of, so I'm just seeing this now after visiting your profile, sorry. I've only glanced over it for now (I don't have the capacity to read it in full right now, much less the whole thread), but I actually agree with the premise, if I understood it correctly. PvP missions would be a great addition. I am unsure how they could be implemented without being DOA because either it turns out too few players are actually into PP PvP, or because if instancing, blocking and the like. And because of the possible pitfalls I fear it will never be enough for those hardcore "PP is PvP hurr durr" types.
