Anything shoulder down that you think would look good cosmetically is the whole purpose behind creating custom bodies, staff creating that many accessories is a waste of time and resources when the option has and always will be available to players.

Wings/tails are also doable by designing custom shields.

Smithing would be pretty neat but I think there's already a lot on the workload of current things they have planned and creating a new job like that would take a fair bit of time as well, so realistically I can't see it being added anytime soon.

I would let them finish balancing current jobs and then go on from there, but I don't think Classic needs a job that in-depth especially because I don't think it would appeal to a majority of the player base.

I don't think the current situation is really that bad, since the release of the Pyrat quest players could in theory have earned nearly 1,000,000 gralats from it alone, earning 365k in a year is enough to cover all the holidays and the Pyrat quest is very fast and easy to do. Alongside this, farming has always been a very good method of earning Gralats, ideally while doing the Pyrat quest you use up your bombs in your farm every time they fill up, with 99 bombs you get 297 uses from a horse or 495 uses from a 2p mount, the guild house I use has 40 grass spots and for every 10 spots I use 1 bomb blow, that's about 70~ uses each on 4 rows of 10 with just one inventory of bombs which usually gets them at least 15+, but even if you had poor luck and they averaged at around 10 gralats each you still just made about 400 gralats right there (normally higher) and you get to do it a few times before finishing the Pyrat quest.

On top of this, with the new loot cap if it does remain at 200, you can make it a daily thing to fill up 200 and sell, then repeat the next day.

All of these things add up and earn you a lot of money, the problem is just players are bad with saving up and only focus on these things when there's an event or holiday coming up.
