Some other things to consider....Skyhawks, both USN and USMC, hauled a lot more than Mk. 82s. Here is a photo of a VMA-223 Skyhawk from Chu Lai, 1968, with a drop tank on centerline and two rocket pods: http://www.a-1-6.org/1-6th%20site/1st%20bn%206th%20inf%20web%20site%20off%20line/cdcas.html
Here's a relatively uncommon loadout on a VMA-223 A-4E(the same loadout could be carried the same way on an A-4F). Centerline tank, inboard stations both carry Mk. 4 20mm gun pods and outer stations carry rocket pods: http://www.aoadecals.com/32010/COVER-32010.jpg
Here's a VMA-311 Skyhawk at Chu Lai hotpad, All 4 wing stations have Mk. 77 napalm canisters and the centerline station has BRU-41 MER loaded with Mk. 82 Snakeyes: http://a4skyhawk.info/sites/default/files/images-a4-unknown/a4-vma311_19.jpg
Note that even though this is a different squadron, this would not have been an uncommon loadout for the unit you're doing. VMA-223 was at Chu Lai around that same time and would have flown the same types of missions as 311 did.
Here's one loaded the way you originally asked about:

There are so many options that you could choose from. Another option is a jet that just came back from delivering presents....with empty MERs on the centerline or inboard pylons and empty rocket pods on the outer stations.
This one was probably not such a common sight--this was taken in 1969, it's a VMA-223 Skyhawk with centerline tank and a pair of AGM-62 Walleye glide bombs on the inboard stations. Outer stations are empty.

One that you won't find a whole lot of use on the Skyhawks was the Mk. 81 250 pound bomb. They did have the ability to carry other weapons as well, like cluster bombs and AGM-12 Bullpups. A note on the Bullpups, there were two basic versions. The AGM-12B could be carried on all stations, but the AGM-12C could not be carried on the outer stations. It's also important to note that bombs of different types or sizes were not mixed and carried on the same MER at the same time.
