I wouldn't on my first attempt...too many little details to have to pay attention to for one beer let alone two. But down the line, go for it. The easiest way is do a partigyle, and make 2 beers from one grain bill. A strong beer from the first runnings and a lesser beer from the second.
I go over how to create two recipes from one batch here,

But you don't even have to get that complicated, once you get a handle on things like Ibus and stuff. When I did my 50th birthday Barleywine chronicled on the link in my sigline, I did my second beer "on the fly" using brewing software, a refractometer and my IBU/BG chart.
I was able to take a preboil gravity of the second runnings, calculate what the og would be when boiled for 60 minutes, then used the chart to figure out how hoppy I wanted the beer, then used software to figure out hop additions to get there.
Oh and we did 5 i gallon batches of mead, inluding one where we boiled the honey for several hours until it was black to make a 15th century brocet (burnt mead.)
This is what you will be able to do down the line...but on your first AG, "I wouldn't try this at home."
