1024 samples is way too high. I guess you had to put high to get rid of highlight artifacts comming from the hdr image.
You should clamp your hdr image by converting to a LDR format and blur it
So you can reduce the number of sample to 128.
Is your character animated ?
I mean you can still bake the bent normal and use the mib_bent_env shader and plug it in the ambient slot.
You can create UV with the unique UV option.
