It's fine and natural for casual conversation, but there are some things you might think about to avoid being guilty of lazy English.
First, using words like thankfully, luckily, and hopefully that way doesn't make literal sense, even though it's common in informal conversation. It's saying that you're trying thankfully, when what you mean is that you're thankful that you try.
But is trying what you're actually thankful for? Maybe you mean that you're thankful that you're the kind of person who tries - or you're thankful that you have the time and circumstances that allow you to try.
So to make the statement absolutely logical, you would need to rephrase it or simply remove the word thankfully altogether.
