Need others opinions

Hi, I was thinking that sometime in the future (not right away, maybe around Christmas time) I would like to set up a FOWLR tank for my angelfish. I was originally thinking of a 180g. I already have a 6" blueface angel, 6" queen angel, 4" emperor angel, and a 2" coral beauty. I know I want to add a majestic angel and a flame angel. Possibly a goldflake angel.

Now I'm wondering if a 180g would be big enough, what do you think? The plan is to get another tank for my angels because I think they are a bit crowded in my 230g with all my tangs. The reason I was thinking a 180g and not another 230g is because I can't reach the bottom of my 230g tank. Any comments would be great, thanks Laurie.
