what size tank/sump and how much rock do you have? A single dragonet will eat hundreds of pods in a day. A single bottle of reef nutrition carries 2000-3000 if i remember correctly. You will need to seed heavily, before even adding one, make sure they are established before you add the second as they will decimate them.
I have a female psychedelic and a male scooter. Ive had the male about 2 years give or take and the female will be a year next moth. They are a pair videos below, the male will defend the female so she can eat, which will cause some smaller fights. I have these two in my 120. I add pods monthly.
When i first got the female and they became a thing after she came out of hiding. Notice the male defending the female from the snowflake on the right. He also wont eat by the female.
And this is them a few weeks ago before my water change. This is the male defending the female from my lawnmower. I do not think they can breed since they are different but they are in the same family, would be some funny babies LOL.
So you could possibly do it, if you had a large enough tank, have it established, and get pods monthly or even bi weekly depending on consumption.
