You can try to duplicate the doepfer melody and hi-pass one of them and cut it big time say from 0-600, then on the duplicate you run it on another channel with a low-pass filter instead working from where you cut with the hi-pass filter, then get rid of the worst unneeded bassey regions in the sound and sidechain that channel with the kick and lower the volume on it?

There should be lots of ways really but hard to nail it without being able to hear it.
