[Q] Porting kernel?



Hi guys, I'm doing a Cyanogenmod 12.1 porting for my device that is unsupported. I can build everything and I get a flashable zip but I'm using a prebuilt stock kernel image extracted from the stock lollipop rom. After flashing, the phone does not boot and It's impossible even to access to logcat, so I think it's a kernel related issue. My question is:
- I have the stock kernel source (v.3.10) given by the vendor
- I have the cyanogenmod kernel source (v.2.69)
Do I have to build the stock kernel or I can build the cyanogenmod one by merging the drivers modules and others stuff?
And if I flash a wrong kernel image can my device become unusable?

I read that is not fair importing built kernel modules from other kernel version, but if I merge the kernel trees, is it the same?

Sorry in advance if my question is a noob question ;)
