Well, a friend and me found a funny way to pull Bloodboil from above his room.
I think every class which has a combat-pet can do this, it is yet tested with hunter and frostmage.
Here's how to do it:
You simply jump up to where the skeleton is in the picture (it's on the side where the entrance to Bloodboil/RoS Trash is).
When you're up stand like this and summon pet:
The Pet will somewhat fall down and pull Bloodboil. He will try to onehit you through the ground, but you can prevent that by running back to where the ashtongue vendors are (this is only tested with blink btw).
This will end up in a situation like this:
And if you start running really fast (I did it with blink only, so you could get quite further with movespeed pots or hunter aspect) you can pull him to almost anywhere in the lower temple:
I guess you could pull him out to supremus or whereever you want, it can just happen, that one of the beasts adds. I had this situation one out of four tries.
I doubt it has a lot of advantages to pull Bloodboil to a strange location (fun factor maybe) but at least you can skip the trashmobs, although they aren't much.
Greets,
