Catch can alternative?

[2kx2]

Does anyone have any recommendations for eliminating oil blow-by for my maggied LS6? I noticed oil on my IAT sensor and have put catch cans in place but they look out of place and I would much rather get rid of them.

Are there any ways of doing this without having to run these ugly catch cans? It's bad enough having so many hoses and wires running all over the engine compartment.

Thanks in advance.
