So having the 8ohm head connectors left/right going into each 4 ohm cab should be fine?

I recently purchased a line 6 4x12 cab to go with my HD150 head, I also have a raven 4x12 and thought I would try to hook the head up to two cabinets. This looks kind of silly but I dig the tone mixture from these two different cabs. I have used this a little bit already at low practice volume but if I can I would like it as a rig in my band setup. I am very worried about damaging the cab/blowing speakers etc. and would like to know if this is safe to use. I have attached some pictures of what I'm dealing with.
