   I'd educate your customer that this is not kosher.Crown is for the "crown" or pinnacle height of the ceiling. If he/she is insistant, run a mock-up first.The vertical section will have a chevron and be coped both sides to meet the horizontal crown.

   The crown down the wall would not look correct. Can you use a large cove instead? I think your looking at 6 lots of 45 degrees meeting in a "star". Might be better to install a cube in the corner and butt into that.

   This is kosher 'cause this what your customer wants, and he/she has enough faith in you to ask you to do it.

   I think the easiest way to solve this problem is to use something called a "Bollection Moulding". These mouldings are typically used around fireplace surrounds to trim masonry, but you can be creative and use them elsewhere.

   Here is an example http://www.architecturalfacades.com/html/mntl_bol.html

   I must add something here.

    Just because a customer wants something done and will pay you does  not mean it is appropriate to build it their way. It is you, the woodworker, that  has an understanding of form and function and the appropriate choice of materials. That understanding has to be conveyed to your customer who will then appreciate such knowledge and respect your judgement. And will offer you repeat business.

   You're going to have problems with this one if you take the job without thorough research first. Good thing hyou posted the question. You might also want to post it over at Breaktime -- there's a few trim/finish carpenters over there.

   The big problem is that crown molding is not appropriate for a vertical corner. The vast majority of the pre-molded crown is not designed to be hung at a 45 degree angle to the wall and ceiling. It covers a different amount of the ceiling than the wall. If you put this stuff in a vertical corner, it will cover a different amount of the left wall versus the right wall.

   That would be just plain ugly.

   And if you use a corner molding in the vertical corner that is different than the crown, then calculating all of the compound angles will be almost impossible.

   It sounds to me like you need to design and mill some custom molding that can be used as both crown and inside corner molding.

   Of course, you do have a molder that can do that wide stuff, don't you? And a local toolmaker that can do the knives? And a customer that can cover all those costs?

   Unless you're the lead dog, the view just never changes.

   While I agree with everyone here, it's not what it's designed for, it's not the prettiest thing ever, I have to disagree with those who say just because the client wants it... especially if the client is your wife. Nothing personal guys, but I like to eat, and it's for her kitchen so I too had the same problem, and I was stumped. I logged on here looking for someone to save me and it didn't look good. Soooo, I decided to look at the problem from a different angle. I had to stop looking at it as a crown molding guy and look at it more as cutting a frame, and that's when it hit me. instead of cutting upside down and backwards, cut it with the top to the back and design side down. Wife is happy, Food on the table, all is good. Carry on my friends.

   I also ran into this situation today, a boxed furdown for a/c duct. So yes there are times you need to tie in a vertical into a horizontal run on crown. Still working on the puzzle and I will eventually figure it out but any ideas would be helpful.

   I do hate when users revive ancient threads rather start anew, but I will tell you it's not possible if the the crown has 3 pieces meeting in the corner unless you have a symmetrical molding and most crowns are not, not even coves. No matter how the cut it the profile that adjoins the wall in the horizontal pieces will always be mating with the profile the adjoins the ceiling on one face. There is no magical way to cut the joint that eliminates that simple reality. The only solution is to use plinth blocks and terminate the moldings square into that.
