I'm not sure how you would mount a heatsink but the PCB copper is
already doing this job. I think you are overanalyzing a problem that
doesn't exist. Even if you had 6 sensors at 50 mA each (AVG) you are
only talking about 300 mA - with a 5A regulator. You're worried about
a 5A regulator sourced with a 1A power supply.
Hook 'em up and see if the regulator gets hot. I'll bet it doesn't.
