Advice on my RL6815 rig (ohms, wiring, etc)

Hey guys,

Long time reader, 1st time poster! I'm having quite a dilemma that I'm unable to figure out completely. I recently purchased a Carvin RL6815 Cyclops rig from GC, however in placed of the standard Red Line head, there is an Ampeg B2R head installed. For those unfamiliar with this rig, it is a 2x8/1x15 setup. Anyways, when I picked it up, only the 15 speaker was connected, however I'd really like to try to have both sets of speakers running. The only issue is that due to the ohm rating (the 2x8 connection is 4 ohm) and (the 15 connection is 8 ohm), I believe I'm running at the typical 2.67 ohms for this setup. The B2R is rated for 4/8 ohms. That said, the cab has dedicated inputs for the 2x8 and the 1x15, so I'm trying to figure out what the best route is to get the entire speaker system running while spending little if not any money in the process. I obviously know that running at 2.67 ohm is a no-no, so leaving it the way it is should not be an option. I'll post some pictures of the setup and the connections to give better insight. Anyways, am I approaching this correctly? Should I be treating it as though each connection is two separate cabinets? I would like to avoid having to buy a different head, however I'm not opposed to purchasing a replacement 15 speaker to bring the ohm rating up above the minimum if it is actually possible. I just wanted to see if there was any way of bypassing spending any additional money and if not, what should I get to make the rig work the way I want it. Any insight or advice on this situation would be extremely appreciated. Here are some pics

Remove the B2R...install a Carvin BX1500 with two independant amps that can be controlled seperately and biamped.

Changing out the heads isn't an option at this point. This is just a budget practice rig that I'm trying to avoid major expenses. Anyways, I came up with an idea that I want to run across the members of the board.

The 15" is 8 ohms and each 8" speaker is 8 ohms. They're currently wired parallel, which gives the total load at 2.67. However, what if I were to wire it to a series option with the 8s and give it a rating of 16 ohms, then giving the overall load of 5.3? Finally, I also had the idea of wiring all three together for an ohm load of 12.8. What would be the best option?
