How to merge lora into Wan2.2 unet model?

I'm using ComfyUI to try and merge a loras into the wan2.2 high and low models (Wan2_2-I2V-A14B-HIGH_fp8_e4m3fn_scaled_KJ etc.). I'm using load diffusion model->lora loader model only->Save model. but fails to save. I've tried using KJ nodes versions as well but also fails. Anyone knows how to merge loras into the model? Reason is i'm trying to reduce the amount of loras i'm loading to reduce calculation time. There are 4 loras I always use between low+high. Having them merged in will speed up calculation about 24% for me. submitted by /u/SkinnyThickGuy [link] [comments.
