Marquise Halo?

[Taylorbug!]

I am considering having a halo added to a 2ct marquise that is currently custom made. Any pics or suggestions would be most helpful. My jeweler has suggested using either 1 or 2 pt stones. Are they large enough to compliment the center stone?
Ignore the black nails...was on my way to a halloween party!
