Now the hard part. How does one create an Impedance, which decreases
"slower", for frequencies close to zero but then decreases "faster" for
higher frequencies, than the simple parallel RC-Circuit?
Is there some kind of procedure like the one for syntesizeing LC-Filters
(Butterworth, Chebychev,..)?

For emulation modeling, there exist programmable resistors,
capacitors, and inductors. Is that what you have in mind?

I think he is looking for slopes of less that 6 dB per octave.
