Would Blizzard consider any other quest adjustments for hardcore?

I received a new quest chain at level 20 on my rogue to acquire the thistle tea recipe. It was yellow to me at 20. When I arrived, I was surprised to see the malformed was 23, but no worries. Picked the key, and headed in the tower. After some real tight quarters and wiggling, I managed to make it around maybe half a dozen level 24 guards, ending up at the backside of Klaven. I successfully sapped him, and as I pulled his journal from the box, he broke free and knocked me pretty hard. I was able to jump the rail and down to the ground, but my potion and sprint were not quick enough for the guards that could see me. I made it to the doorway, and fell. I was able to stream the last part with friends, and we all had an entertaining time.

In the end, it was one of the most fun moments I've had in hardcore so far. Almost out the door! A few days later, it got me thinking whether or not I should have attempted it... which made me think that it would be great for the players if the quest color reflected the mobs... which would have been red to me at 20.
