yes: 
ftp://upload.mplayerhq.hu/MPlayer/samples/MPEG-VOB/sample_aac_streams/er02.ts
contains 2 video streams (same image but resized).
I had to add -an because the aac stream is detected incorrectly, but 
the sample is good enough to test

 ./ffmpeg -i /mnt/linux/home/nicodvb/tss/aac/er02.ts -an  -vcodec 
copy -y -f mpegts x2.mpegts   -newvideo

both video streams were copied correctly


Other test: copy the first video stream and encode the second one:
./ffmpeg -i /mnt/linux/home/nicodvb/tss/aac/er02.ts -an  -vcodec 
copy -y -f mpegts x2.mpegts  -vcodec mpeg1video -s 800x600  -newvideo
