Will I be able to sell a mod created for FLARE?

Will I be able to sell a mod created for FLARE?

Hi, I am a freelance artist who is interested in using FLARE to create a mod. In this mod, all characters, monsters, animations, environments, and effects will be created by me from the ground up. It will feature an original story, as well as original spells and progression system. I have chosen to work with the FLARE engine due to it's ease of use for a non programmer and due to the core mechanics of the engine aligning with my design goals, which is a hack-and-slash RPG.

My question is whether I would be able to sell this mod as a pay-to-download. I wish to approach the project in a professional manner, and have given myself a timeframe of July to December 2015 to work full time on the mod. 

I am also open to other options if selling the mod is not possible, as long as I am able to stay afloat during the months that I intend to spend working full time on the mod. Thanks!
