This got me thinking. What if any attack roll was d20 and d6? You could roll both dice at once and consult a table. You'd add all relevant bonuses (for level, STR, magic weapon, etc.) to the d20 roll. I like AAC, but you could easily change the table to work with your preferred AC system.
Below you will find a mocked up table based upon Fenway5's work. I've added my own twists (tinkering with the damages a bit and allowing saves for some effects). I may give this a try during my next game night.
For your consideration:
