Thanks! And some suggestions for the workflow
I'm glad I found this because I was about to try the same thing. When comparing your workflow to the one I put together yesterday, I think there are some things that could simplify it for other users.
First is the Crop (mtb) node. I think the standard Image Crop node should work just fine. This is especially important because currently the mtb nodes have an error when installed from the manager (known issue).
Second, we can use the Comfyui-In-Context-Lora-Utils nodes to somewhat simplify the process.

Thank you for the optimization! Using the native crop node instead of MTB really makes sense. As for ComfyUI-In-Context-Lora-Utils, I've used it before, but there was a bug at the time, so I switched to the node with the same effect from Easy Use and got accustomed to it. For similar reasons, I use the inpaint and crop nodes. But your workflow is much cleaner—great job!
