Don't worry about the bleed, the combination of both mics will, or should sound real nice.
I get some great results by putting 1 mic in front of the guitar (or the amp).
And or course 1 mic for vocals. Now try putting 1 more mic out front to catch a little of both, about 5 to 6 feet away from the guitarist, sometimes as close as 3 feet works too.
I find that the mic that gets both, is alot of the time REALLY nice. And is the best track alot of the times.
Sometimes I use 2 mic's out front and listen back at mixdown and use the best of the two.
But 3 mic's should make it sound pretty nice. IMO
Lastly it wouldn't hurt to use some sort of direct box on the guitar.
Making it a total of 4 tracks

Just be careful with the phase anomolies ... check the tracks in mono to be sure nothing cancels out ...

If you have a pair of figure 8 mics you can set up where the focus of one is vocal and the other is guitar. Set the mic where the nulls pick very little of the unwanted signal. I have done this a few times with good results.
