There's a stat that does exactly this, using launch angle and exit velocity, called xwOBA (expected wOBA, as you called it too).
Here's the leaderboard from last year. It's probably the best hitting statistic we have publicly right now.
Speed also seems to have a noticeable effect on the difference between xwOBA and their actual wOBA.
