So far my ideas for champion quest 6 would probably be ending at magen,but I don't feel like it would be an interesting champion quest.
Does anyone have any suggestions for it?(it must be what is already possible to set as a goal in the quest)
I would prefer an unrestricted quest so no purple if possible.
I would prefer if the quest lasts ~ 2 months so people have time to realize a champion quest is happening for rebirth characters.

If you're curious what the champion's quest is see this post from the old forums, http://aranock.forumotion.net/t3089-champion-of-champions-quest

So I thought about the quest for a while, so far my idea after discussing it with some people is,
Finish all labs
finish Castle 1
min rank Col
rewards by kin(1 per race)

any rebirthed characters and new non-rebirthed characters may join.

Would anyone have a problem with this champion quest?

Well, you know how i feel about champion quests in general.

I'd say lets focus on the warlord rebirth first and ensure it's all working properly.
