Is it possible to buy cup hooks with an extra-long screw (say 1"), suitable to pass through plasterboard and get a secure fastening into a joist above? The hook itself only needs to be, say 1/2" to 3/4" diameter.
Solid brass preferably.
Many TIA -
I solved this a different way using plasterboard type rawlplugs to fit the cuphooks for xmas lights in the house Hooks are put in and taken out at same time as lights
May not work for you depending on load applied to hook

If you're talking about simple on-piece cup-hooks, probably not - but these wouldn't be made of solid brass anyway.
However, if you go to something a bit heavier duty - like hooks for curtain ties, some of these are solid brass and a flange with a tapped hole in the back. A double-ended screw - machine thread one end and woodscrew the other - then screws into the flange.[1] You may be able to get longer double-ended screws. Alternatively, you could use use a long machine screw - and screw it into a hollow anchor like
Look for "vine eyes" (as Homebase call them); and a hacksaw, but I've only seen them in steel. That's what I had to do last time I had a similar problem of hanging a fluorescent light fitting.

They are available in stainless steel. The advantage of brass or stainless is that it won't rust. As you suggest, using vine eyes or similar after modification with a hacksaw (or AG!) provides more options.
I should have looked harder at the Homebase website. They do a 50mm brass cup hook, just as the OP ordered:
