165gl FOWLR questions

HI All
I know this is basically a REEF FORUM but I respect your opinions so thought I would throw this out there.
My New project is a 165gl/with 55gl sump FOWLR setup ( sump will be another 30gl of volumn)
this tank will have live sand, and plenty of Rock (at least 100lb but probably closer to 130) it will also have some artificial corals in it.

I am probably 2-3 months away from first fish going in but want to start planning a bit. REALLY undecided as to my direction of tankmates so am wide open to suggestions and even a completely new list, actually the more the better.
Here is my first thoughts of a tank setup - again, I am open to any and all suggestions.
we have been wanting Puffers for a while so I would like to see if they will fit or not. if they are going to restrict many, many other tankmates please let me know as I have no problem squishing the idea. BUT here is my first list

Dogface Puffer
Blue Spotted Puffer - research tells me they will co-exist (thoughts on this)

Flame Angel
Lemonpeel Angel - will these 2 co-exist (and obviously I need to know if any of the fish listed will have problems with each other)

Scopas Tang
Kole Yellow Tang
Lavender Tang

Lyretail Wrasse

Goldhead Goby

now I must say our family with 6 grandkids and us being Foster Parents
we love to have a full and active tank with MANY fish in it. so if this all works together, can I add more? how many more? any suggestions would be helpful.
we want this to be a point of attraction in the family room.

Thoughts and recommendations and remember if you want to give me your own list PLEASE DO.....

look forward to seeing whats on your mind..
