Hi and welcome to canreef!

I would be cautious about the lunar jumping as when they get bigger there will be agression towards each other, from what I hear the dragon wrasse can be pretty mean when it gets larger probally not to the trigger but the lunar is a known carpet surfing wrasse. You may chance it and see what happens but I would keep a close eye on both fishes and ofcourse the most important thing is keeping a lid on your tank.
