No you don't want to use profiles for this.
Use module-remap-sink to create a virtual 2 channel sink that maps it's
front-left and front-right channels to the chosen channels on your real
hardware. Remember to add the remix="no" argument when loading it too.
Something like (from memory so double check on the module docs wiki page
incase I've mis-remembered something):
load-module module-remap-sink sink_name="LCD" channels=2
load-module module-remap-sink sink_name="StereoSystem" channels=2
You will then have three sinks in total:
Your 5.1 system
and can move the streams around as desired.
