The technique you describe was one variant of FIB Compression. It got some attention around 8 years ago on the IRTF Routing Research Group and some more attention about 5 years ago when several researchers fleshed out the possible algorithms and projected gains. As I recall they found a 30% to 60% reduction in FIB use depending on which algorithm was chosen, how many peers you had, etc.
A good start would be killing any /24 announcement where a covering aggregate exists.
