I would advise if you want to keep your Damsel do it. I've currently got two Damsels (domino and four stripe) in my tank with a Clarki Clown. The clown is definitely the aggressive one - not the Damsels. They picked at each other a lot for a week or two but have since established territories and now stay out of each others hair. The longer I stay in the hobby and chop up special diets for some of the more specialized fish the more I appreciate my Damsels for what they are - colorful, hardy and super easy to care for. I've had a lot of more exotic fish in my tank over the years but the one constant has been a Damsel or two. I like 'em and I notice there are several new species coming on the market recently.
I've had mixed Damsel/Clown fish tanks for years and they've worked fine. A couple tips:
1) You don't say what type of clown you're interested in. There are many different species. They vary in size and agressiveness. A tiny little tank raised Percula may not fair as well with a Damsel as a bigger more aggressive clown like the Clarki, Tomato, Maroon......
2) I would definitely run with your idea of adding two more fish. As a general rule keeping odd numbers of any fish balances out the power. If you have a bully in the tank simply adding another fish can often cure the problem. Putting a single clown in with your single Damsel will likely result in a battle. Putting two new fish in at the same time should help.
Give it a shot and see what happens. You can always make a change down the line if you need to - especially since your tank is still so new.
