If a different workflow is what it takes to inspire you then hey, go for it. Download the demo and try it out. Now here's why I have a problem with your questions:
If you're proficient with FL Studio and know it inside out, then there is absolutely no reason (no pun intended) to try a different DAW. Reason is not going to help you make better music, only PRACTICE can do that. We all have moments of writer's block but that is just part of the creative process. I found an excellent article about inspiration when it comes to music. Check it out before spending your hard earned money. Here's a quote from the article:
"Stop looking for it; stop waiting for it to arrive; it's not coming. Now get down to work. The composer is a person who composes, who exerts effort towards making a musical composition. Inspiration is not something to be sought after, but a term that other people label your product with after it is all done. "Wow dude, that was inspired!"."
