predict.c is intra prediction, not motion. Yes, you could modify that. 
The decision of which intra prediction to use happens in 
encoder/analyse.c:x264_mb_analyse_intra(). The decision will still work 
with modified prediction methods, as long as you remove 
pixf->intra_satd_x3* and pixf->intra_sa8d_x3*, which are optimizations 
specific to the h264 versions. (just removing the initializions from 
common/pixel.c is enough).
