What if I've tried to increase the prompt adherence in <a target="_blank" rel="ugc" href="https://civarchive.com/models/795765/illustrious-xl">Illustrious v0.1</a> and its siblings? It's only a test though, because I'm not entirely sure if I did it correctly. :)Left image - original checkpoint, right image - modified checkpoint. It seems the 'characteristics' of the original remain in the modified model, but prompt adherence is better for the most part.Another observation - VAE inclusion gets 'reset', the resulting checkpoint doesn't have it.

Illustrious v0.1 and its variants sprinkled with Illustrious v2.0-Stable CLIP

Experiment on the great checkpoint mix - <a rel="ugc" href="https://civitai.com/models/1219622?modelVersionId=1935696">Kageillustrious (Illustrious XL) - v6.0 (NLXL Version)</a>. Result is interesting! :)
