As Boyd says in his book on Chebyshev Methods: when in doubt use Chebyshev polynomials.
I use Chebyshev polynomials extensively in finance and have tried problems like MNIST with Chebyshev and they get close to CNNs in accuracy.
ApproxFun Julia package pretty cool for Chebyshev work:

What do you mean by close to CNN?
What is your architecture? Is it just a fully connected layer of chebyshev?
