People have asked me to do that in the past, and I told them they could only buy a custom from me if I do it in my own style... They showed me a painted custom, so I suggested I take the same character (not owned by the customizer) and make it a outfit, give accurate expressionism, and a more accurate and elaborate hair style...
You might be able to have someone recreate it in their own methods, quality and skill but don't be too disappointed if no one's willing to copy it. You'll actually want them to change it up quite a bit and only have it vaguely resemble Trillion's work...
As a matter of fact, I commissioned Trillions last year, so she might still be around and available to do a custom like that, for you. It's worth contacting her!
