Best and simplest user solution to big outdoor stages is to hook up a powered monitor pointed at you.  If the PA doesn't provide enough or any stage monitoring, so you can move around without being too loud for yourself or too quiet, try this simple solution.  Get any inexpensive powered monitor with either a 10" or 12" speaker, plus a variable horn/tweeter. 

Most of these monitors will give you a much wider range of coverage and it will give you at least two sound sources that you can "spread around" in order to hear yourself well over a much larger area as well as help your bandmates hear you better as well since it will be pointed back towards the band.  I'd say just get an external monitor cab with variable horn /tweeter level and plug it in facing you, but I do not know if your amp has the capacity for additional ohm loads.

Another even more simple, but perhaps not a nice cosmetically, is to use a baffle panel.  If you have one you can angle it so that you direct sound is reflected around more.  If you have two, you can literally cover the entire stage by making it into a "V" shape right between two or in the dead center of one speaker and this will keep your ears from being blown up in front of the amp while sending the sound in whatever combination of directions you need to to hear best.  Using various coverings, like a thin sheet of fabric or even cardboard will change the overall tone if it is still too piercing with just the baffle alone.

None of this is Line 6 Dream Rig approved. LOL, but they are some old school stage tricks to get the most and spending the least.

I hope these "tricks" help you and anyone who might read it having a similar situation,

I went with the combo. A few months in now and I'm really pleased with it. I play in a power pop band and my tone is usually clean or slightly crunchy. It has worked out well. However, we recently played a really large venue on an enormous stage. I had the combo on my amp stand and it was very directional on stage. If I stood directly in line with the combo, it was so loud that I was way too aware of every nuance. If I moved about a foot outside of a direct line, I could barely hear it. Not sure a larger cab would've helped but it was a weird experience.
