Firstly "Discworld". No space (or hyphen, as I've seen elsewhere), at least for the particular Discworld we're talking about. (In contrast, those Discworld denizens who have any reason to know of our existence (i.e. the wizards who accidentally called us into existence) call our our world (both this planet and the entire universe) "Roundworld".)
A world and a mirror of worlds, and as mentioned, anything you see in Pratchett's work is going to have some form of inspiration from the real world (very little could ever arise in a vacuum). Although his most ☼MASTERWORK☼ pieces of reference are often reversed/subverted/extended/combined or otherwise not as you'd expect, so the .303 bookworm, republican bee, ambiguous puzuma, quantum weather butterfly and vermine (even characters themselves such as Death) aren't just mere copies of the real world examples but have their own twists. I would guess that DF players are also in the likely-to-read-Pratchett group. (Although I'm not suggesting that all of us
like him and his works, but I confess that I do.)
So you have three main problems when suggesting things from the Pratchettverse:
- There's probably an IRL source that's the original source of the more general concepts.
- DF is Toady's work and not Pratchett's, so putting explicitly Discworld-variety things in (while maybe possible as a fan-mod[1]) would be fair for neither Toady nor Pterry.
- Anything practical (or potentially so, in known future development arcs) you can derive from Discworld has probably been suggested before, anyway (and I've definitely seen golems suggested[3]).
Not wishing to shoot you down, but ideally you should search for the previous Golem thread(s), check out what's already been mentioned and if you
still think there's something you can add then you've got the opportunity to either Necro that thread or start a thread like this with "I've read <thread-link>, <thread-link> and <thread-link>, and I would just like to discuss <new aspect>..."
FWIW, on the basis that this will actually be a new conversation on Golems, I'm wary that this is another "money for nothing" item. It should need significant effort. However you feel about the common glut of stone crafts, you certainly don't want it to be simple to create (or maintain) a whole load of golems.
Pump-powering golems should not be (like "Mister Pump" of Going Postal fame) be set in place and keep going, regardless of environment. If the effort is not within the same order of magnitude of either setting up a mechanical power-feed of keeping a happy dwarf (or team of them) capable of manning the pump for as long as necessary, then the idea needs balancing so that it is.
[1] Pterry doesn't mind people making fanfics, and tolerates the likes of the Discworld MUD ("MUD? What MUD?"), and is not horribly possessive of his IP in these regards. All as long as no money is made[2] and there's no possibility that he can be accused of stealing someone else's ideas. Such that even "it would be nice if..." suggestions made in forums he has frequents in an on/off nature are discouraged most heavily by the regulars. Still, a bit of netiquette helps in the firt place.
[2] And hoping that those who write their fanfiction (even slashfiction!) will go off and write their own things once they've finished with the derivative works.
[3] Searching the forums for the intended idea will pick up posts. However friendly we are as a forum, here, people get tired of saying things like "Yeah, gunpowder's been discussed ad-nauseum", and the like.
