Is this a terrible fish combo?

[Whatigot]

used to keep 2 clowns, 1 clown goby and an rg in my old aquapod.
No aggression from anyone in the year I had it.
Used to do weekly 10% changes though, as I was new to reefing and found maintenance fun back then.

RG is my FAVOURITE fish (got a harem of 3 right now), I would think that it's worth a try if you think you can keep up with water changes as that IS a lot of fish for a little tank.

FYI, a dsb will do WONDERS on a smaller, heavily loaded system, not to mention help in the natural food supple (i.e. less feedings of nitrate rich foods from you).
