Simply buy RevisionFx' Twixtor or just accept the long render times using AE's own slow routines. Some things just can't be changed.
Thanks for the tip; I’ll check it out!

Re: Frame Rate Conversion from 18 to 25 fps
I checked the suggested website and – although that product looks great – noticed that my wallet started to protest.
Surfing the internet further for solutions, Creative Cow came to rescue with a video tutorial of an existing feature in After Effects: http://library.creativecow.net/articles/harrington_richard/Converting-Frame-Rates/video-tu torial
Following that method and then importing the AE composition into Media Encoder (which provides for an additional conversion to HD 1920x1080 and using the codec in my editing card Blackmagicdesign Intensity Pro outputting to a TV-monitor) I achieved exactly what I wanted.
The rendering time of the combined AE en ME is now some 1½ hour instead of close to 1½ days!
