Default EOS 3 Stable + Bigpart

Is there a bigpart boot.img available that can be used to replace the standard boot.img in the EOS 3 Stable release?

I have tried the one from CM11 and EOS 4 bigpart roms but they don't work.

I'm finding EOS 4 way too laggy and EOS 3 runs perfectly smooth (even if it is only 4.1.1)
