Seeking guidance

Hello, I extended a recent paper that evaluated two models on certain characteristics of LLMs by using a different open model they didn’t test, and I also fine-tuned it (which they didn’t do). Got some interesting results that adds to current knowledge meaningfully. Would this kind of extension be publishable as a short paper or preprint? Also open to suggestions, criticism on how to frame or evaluate it more rigorously. Please DM. Thank you so much!
