Sounds like you might be pointing more at your femoral artery that way, but the only way to get this figured out is to try it with your gun empty, safety-checked, and no ammo in the room. Short of a true cross-draw position, (which doesn't conceal as well for me anyway, and has other liabilities) I don't think you can avoid the dangerous aspect of any variant of AIWB. On the other hand with the right holster (long enough, perhaps with some kind of pad added at the muzzle end) you may be able to avoid sweeping yourself most of the time.
AIWB does require great care in training and extra cautions in holstering. A lot of people change guns so they have a hammer to control for added safety. There is a must-read, huge thread on AIWB at the pistol-forum. The first few pages are a very good discussion of the basics, much of the later pages are about holster choices. There are techniques for minimizing the danger in drawing and holstering.
If you can train up to a 100% consistent and safe presentation and re-holstering of your gun then AIWB is worth a look.
