In that case I would rather recommend you to sell the great works you can't make room for to other civs. The AI is willing to pay absurd amounts for them, and every great writer/artist/musician can create more than one each. Should definitely be able to give you 3000-5000 gold per person in that case. Though this only works if a) they actually have that much money to give you (gpt included), and b) enough slots to hold the great works themselves, otherwise they won't buy it (obviously/fortunately). But I did that a few times in my Deity win as Russia so evidentially it's doable (though if/when they patch the AI's trade values this should probably get nerfed, though the same can be said for unit selling)Just delete your extra great persons. They automatically give you gold.
Also won't work in multiplayer
