I believe the relevant question is if it is technically possible to
use the existing asm optimizations for the existing tinterlace
filter in your new reinterlace filter.
If it is technically possible, then the asm optimizations are
used if FFmpeg was compiled with --enable-gpl and are not
used if --enable-gpl was not passed to configure.
In both cases, an interlace filter exist.

Above solution seems worse than adding a new filter for
license reasons, something not all developers are opposed
to.
