Adding the fish at certain times sounds good. It all boils down to what you can get from your local reefers/LFS.

My experience with out using a skimmer is you'll need something to keep your nitrates downs.
With using a wet/Dry filter your nitrate well creep up.
Having lot of rock and flow for filtration is good.

Biopellets are a good source to reduce nitrates.
There are many other sources way also.

As for adding fish. Heres how i would do it.

First: Yellow tangs x5
Second: Powder blue
First: Regal tang
First: Blond naso
Second: Yellow eye kole
Second: Orange shoulder
Last: Emperor angel
Last: Majestic angel
First: Long nose hawk
Last: Long nose butterfly (Keep in mind THat they prefer an established tank)
Last: Copperband butterfly (Keep in mind THat they prefer an established tank)
First: Black and white chromis x10
Second: Flame angel
Second: Bi color angel
Second: Elibi angel
Last:Green mandarin in time of course(Keep in mind THat they prefer an established tank)

When adding fish i also recommend doing it at night time. To Cutting down on aggression. Feeding lots if the first few days helps out.

Looking forward to see the build.
