I don't know whether such a pre-made fairing is available, but there's no need to fear the process of fashioning it for oneself. Fiberglass work is a little messy, but trivially simple. Mistakes are easy to fix and creating the forward canopy fairing will take only a few hours spread over several days.
Just do it; you'll be glad that you did.
