UPDATE:
Well, I ran the pair of MRX512m cabs on stands (1 side of an XTi2000 - 400 watts per cab) and tried two different settings on the driverack and still wasn't happy.
Started out with the Wizard setting for MXR512m tops on an XTi 2000 and a Custom sub.
That didn't sound full outside so I fell back and set it to the generic 2way with a mono sub setting. That was better but I still felt like the tops were crunching and not overly clear or brilliant.

The preset is not going to do much for you. Drive Rack PA doesn't have any Parametric EQ for passive tops. You need to Auto-EQ it in the wizard. MRX lacks some 4k Hz and 8k Hz, among other things. After you auto-EQ and see what the Drive Rack does. It should sound a lot clearer after you boost some mid-highs.
Also, to help MRX mid-high and high frequency project a little better, you could do a custom mini-array like below:
This way you can try to get new results with existing equipments.
By the way, what frequency do you cross-over at? You should try 125 Hz, so the sub takes care of the punchy region.

I like that and have never thought of doing that with the tops.
These subs are low to the ground and since the stage is up over everyone's head at this venue, that just may work.
I'm still on the fence. After not being thrilled with the 12/horn sound today I want to blame my lack of preparedness. Should have set it all up at the shop, played with a few crossover points, EQd it a bit, etc.
Time permitting, I'll set it all up at the shop this week and start toying. Thinking the driverack took the wind out of my sails today.
Thanks again

Recognizing your own lack of preparation goes a long way towards future success.
While the problem may be due to improper processing, it could also be that the 12's may simply be not enough for your tastes.

When you say it didn't sound "full" outdoors, was it missing lows, or something else? My personal tastes are that I prefer the 15 for tops over the 12's, which I find run thin on LF. While they may not be producing sub freqs, they still have to be able to project good mid-bass spl.
As far as "crunching" tops after you changed your settings...it sounds like you need some more time to get it right.

Thats the plan -
UPDATE: Just heard from the directors that it was too loud last week. Not sure if it was the volume spilling off the stage or just the fact that the lifeguard station was 10' from the north speaker. .But what I will do now is bring the cabs in to the center.
If I can't stack them as in the diagram, I will certainly have one on either side of a center placed sub.
Shame the 512m has speakons on each end and not 2 side by side.

Well, as long as we're talking about 512m's...here is a photo (I've posted before) of where I had my 512m's in an omni-direction setup. It was a large parking lot where we needed music and announcements to cover the entire event, and we were located in the middle of the lot.
These little light-weight speakers did an impressive job covering the event. I powered them with a PL6.0. The subs were below (not in photo).
As far as "bang for buck" goes...these are a winner! I use these for side fills, front fills, delays, monitors, just about anything. They are loud and clear, lightweight, and a good price!
For FOH outdoors though, I still prefer at least a 15" top for a little more robust mid-bass. All the MRX line has the same waveguide horn. As far as weight, they are a delight to handle...and even 2 on a pole is well below limits.
I have set them up before in a splayed pattern too. With 70 degree horns, a little combing was evident, but tolerable.
Note: In the photo you can see where I added rubber feet to the side of one of the speakers. It also has the added feet on the angled back for monitor use too.
