Has anyone put flexiglass on their bikes and altered it for use on the street with a headlight cutout? Is this easy?

I'm looking to buy a bike I can ride on the street but quickly convert for track use when I want to take it to the track. The best way I see for this is to hang up the stock fairings and stick some flexiglass on it so when I crash on the track I don't feel like killing myself. I'd like to be able to ride it on the street in b/w track days. A couple of years ago (last time I had a bike) I had a street bike that I would convert for the track everytime I went but I quite simple am not interested in goign through the labor every time now.

I don't want to spend the $ to buy separate track only and street only bikes at this time.

any other suggestions? I'm all ears.
