YES.  Composite is a special command to compose only two images.
    http://www.imagemagick.org/Usage/basics/#composite

However convert is a general on and it also can do image composition,
and repeat it (and other image processing) as many times as needed.

see IM Examples,  Mosaics of Multiple Images
   http://www.imagemagick.org/Usage/mosaics/
this whole section is on overlaying in multiple image in various ways,
including...

   composite   (exactly as you have, though repeating the output image)
   convert composition
   draw image compositions
   mosaics onto a expaning canvas
   flatten onto a fixed sized canvas

All five methods will do what you have requested. Both with -geometry
(whcih is gravity effected) or with -page (which isn't gravity
effected).

Enjoy.
