No, it takes the usefuness of OpenCL away, which is that kernels are 
text strings and compiled at run-time.

Just use PyOpenCL and manipulate kernels as text. Python is excellent 
for that - Cython is not needed. If you think using Cython instead of 
Python (PyOpenCL and NumPy) will be important, you don't have a CPU 
bound problem that warrants the use of OpenCL.
