I'm sure there's a way, but adjusting the beam damping
is easier, for example: \override Beam #'damping = #4
The individual slope still depends on the interval
between the end notes, but you can probably find a 
value that suits you the majority of the time. The 
default value is 1, and setting it to +inf.0 gives
flat beams every time. See the test file below and the
attached png.

Hope this helps.
