A workflow within ComyUI allow to restyle an image. I found using existing nodes I could actually push restyling of existing models.
Models:
LTX23_audio_vae_bf16.safetensors
gemma_3_12B_it_fp4_mixed.safetensors
ltx-2.3_text_projection_bf16.safetensors
ltx-2.3-22b-distilled-Q5_K_M.gguf
ltx-2.3-22b-distilled-lora-384.safetensors
LTX23_video_vae_bf16.safetensors
ltx-2.3-22b-ic-lora-union-control-ref0.5.safetensors
