Could you build this?
No A reusable heavy-lift rocket engine requires propulsion engineering, hot-fire testing, manufacturing, and regulatory launch approval, none of which software-assisted building can substitute for.
What it would actually take: Building a real version means a propulsion team with combustion and materials expertise, test stands for repeated hot-fire qualification, and a manufacturing process. It also needs launch vehicle integration, FAA or equivalent licensing, and substantial capital, so the software side is the least of it.
