Without experiments we would all probably be shivering in dark caves somewhere, wishing someone would invent something to help us see in the dark or keep us warm etc. Even Bohemian Rhapsody was experimental.
That said, I'm not sure the two genres work well together. I might have perhaps a small amount of interweaving but faded out the orchestra to let the rock band have centre (or center in you prefer the US spelling) stage. Then, around 1:54 I would fade the band and let the orchestra shine again.
It seems that creating music requires a balance between that which satisfies the composer and what charms the ear of the listener. Keep at it Pete!
