Could you build this?

No Demodulating digital modulation schemes from raw IQ recordings requires deep domain expertise in digital signal processing (DSP) and telecommunications engineering.

What it would actually take: A functioning implementation requires a DSP pipeline typically written in C++, Rust, or Python/SciPy. Key algorithmic challenges include carrier frequency/phase offset recovery (such as Costas loops), symbol timing synchronization (such as Gardner or Mueller-Müller loops), matched filtering (root-raised cosine), and adaptive equalization to handle multipath and noise. Building this demands specialized knowledge of RF communications theory and discrete-time signal processing.
