Looking for Mag XL-50 Aspheric Lens

This might seem odd but I am looking for an aspheric lens, glass or plastic that will retro fit into a Mag XL-50. I would be fine with replacing the entire bezel if need be. I'd like to to have it in my hands in a few days so something that I can order with express shipping. I did a quick search but didn't have much luck. Any help?

Thanks for the link chris97. I'm somewhat familiar with the Ahorton aspheric lens. It would definitely require a new bezel / mount. I'm hoping to find something a little closer to a drop in or if there is a replacement bezel assembly with a lens available I would go for that.

I have a presentation coming up and I have an aspheric three lens system that I designed that is produced from injection molded optical silicone. It would be nice to be able to contrast that system with something else readily available. I can use another flashlight with a Cree XP-E but it would be better to use an XL50.
