I'd be up for it. However, from previous times this came up on various places I can tell you that the majority of people probably wouldn't like it. The sets and Haedrig's Gift guides people towards their "meta builds" and lets them avoid having to think about choices and skills. Despite constant cries for "balance, variety, freedom" I think that actually a lot of people rather *want* to have no freedom - this is indicated by the race to establish metas and the inertia in shying away from it.
I do my own "non-Haedrig" run every once in a while, by playing up HC (after I've grabbed Haedrig on SC). One season we went to the extreme: me and a friend got a powerlevel on HC to 70, but then started to "play up". It's actually really fun (and challenging) to get ANY gear when you're level 70 and naked! Just getting into Torment 1 took us a while (especially since it's HC - you can't just do chest runs), and it took us a few hours before we had our set complete. Most fun I've had in a while, but you need to really think about skills+items you get and add some math to the mix. Definitely not for everyone.
Btw, Blizzard doesn't like votes/petitions, so that's not gonna happen
