Could you build this?

No Writing a transcompiler or backend compiler from Rust's complex semantics (borrow checker, algebraic data types, lifetimes, monomorphized generics) to COBOL is an advanced compiler engineering challenge.

What it would actually take: A real version requires building a custom rustc backend (via LLVM IR or Cranelift/rustc driver) or an AST/MIR transpiler mapping Rust memory models and call stacks onto COBOL divisions, paragraphs, and data structures. The fundamental bottleneck is translating heap memory allocations, pointers, and concurrency into COBOL's flat, static memory layout without runtime corruption. It requires deep compiler engineering expertise and mastery of both Rust compiler internals and legacy COBOL dialect specifications.
