Yeah, it definitely can be done. Clowns shouldn't be an issue. I would recommend hatching live baby brine shrimp for it too. Having pods shipped may not be necessary, but you could add some occasionally to boost the amount (I would highly recommend Apex/Apocalypse pods!)
I also have heard that the Spotted Mandarins are much easier to get eating frozen (but if you aren't a big fan of those then don't get one).
If you do get one make sure it is really healthy. And I would recommend giving it a bath in methylene blue. I have had the worst luck with scooter blennys, and they ALL never fattened up, and it didn't seem like internal parasites, and there were pods, and I was feeding live baby brine. Methylene blue helps with a lot of misc. issues that may not be apparent right away. I feel like if I had done that they would've maybe survived.
You can get some methylene blue medication, or use the blue part in Safety Stop.
But if the fish is healthy then things hopefully will go well.
For frozen food I recommend Cyclopods, and blood worms.
For some reason blood worms are really appetizing for them.
And you can use Vitachem/Selcon to add additional benefits
