Might you consider adding support for this Klein Tiled Upscaler:
https://github.com/Gavr728/ComfyUI_KleinTiledUpscaler
I've tested it extensively and it does a great job upscaling with Flux 2 Klein 9B, retaining strong fidelity with the original image when using a consistency Lora, whilst adding a good level of detail (whereas using tiling in Krita AI causes faces to shift considerably, even when set to a refine value as low as 20%).
