[Yasen6275]

Is it possible to get composite gadget instead of fixed network or serial ones?

You can try to use /usr/sbin/run_usb.sh to setup a composite device (after disabling the usb-gadget-* services and rebooting). I didn't have much luck doing it though... if you can figure out the correct combination, I'll add a composite device service to the image.
