Bittle - Legs, body polymer materials upgrade

I purchased the Bittle in China and I am at the early stage of installation aiming at developing new skills to teach. One of the reason of my purchasing it to replace some plastic materials the legs and body are made of (it looks PC/ABS material) with high performing polymers to assure a long-term better performance in terms of resilience, impact and creep resistance. My intention is to exhibit it as a application example at Chinaplas in Shanghai in April 2022 at the stand of the company I work for. The company is a manufacturer of high performing polymers (EMS Chemie) . Am I allowed to do it ? Thanks for your quick feed-back
