### What should this feature add?

The standard style transfer and moodboard tools use the Krea 2 API (as @Pfannkuchensack has mentioned). However, there is a local open-source style reference node for Krea 2 in ComfyUI, called [ComfyUI‑Krea2‑StyleTransfer](https://github.com/nkxx188/ComfyUI-Krea2-StyleTransfer).

Is it possible to implement it in Invoke?

~Currently, Invoke lacks two of Krea 2's most powerful tools: style transfer and moodboards.
It would be great to have them at our disposal, if possible.~
