I think any one interval could be made to beat at the same rate across the entire keyboard, but not two. When considering 4ths and 5ths, remember the P4-P5 test for a 4:2 octave. If the 4ths increase in beat speed, then so do the 5ths unless the octave is wider than 4:2. And if the octave is wider than 4:2, so that the 5ths beat the same rate across the entire keyboard, then the 4ths beat faster than the 5ths in the P4-P5 test., and increase in beat speed going up the scale.
