Speakers to go with P50e's in a Deliverance 412

So, my newly acquired 5150 III 50 watt isn't playing well with my P50e's in my VHT cab. I'm looking to swap out two of the four and either x pattern them, or put the WGS on top and the P50's on bottom. I play a lot of different styles, but I'm mainly a metal guy. I'm looking to tame some of the highs in the head and get some good mids, no scooped tones for me. What do I need to be looking at to compliment this setup?
