The best defence on 3-on-3 is to keep the puck, therefore Panarin-Gaudreau-Laine would be quite possibly banned as an unfair bunch.
For the next season, Werenski-Gaudreau-Laine would not be that far off.
Both combination would need a "Jenner" for the faceoff.
EDIT:
Just for fun I checked last 3 seasons stats from Natural Stat Trick (I don't have the paid account to fetch longer periods, sorry!) and for current & recent CBJ skaters these have been the most successful:
Laine 6-2, 75%
PLD 9-5, 64%
Voracek 7-4, 64%
Panarin 8-5, 62%
Werenski 9-7, 56%
Domi 8-7, 53%
Atkinson 7-8, 47%
Gaudreau 7-9, 44%
Jones 7-14, 33%
All these were TOP-50 on NHL during that period in number of OT wins when on ice.
Sample size is not enormous, but I was not totally surprised other than seeing how bad numbers Jones has.
