There is nothing wrong with using the nawcom kernel, Anv kernel has a custom dyld and it does not work with every application.

Your flags look right but also add "std_dyld=yes", it will work the same way as the nawcom kernel.

Custom dyld is a nice project but for me its not usable since I practically live inside Logic.

Just patch the mentioned libs with the amd patcher, i have to patch some extra things with the "amd-ext" patcher to use some AudioUnits plugins though, if you have some problems you just have to go trough the traceback and try to find the lib that crashes your apps, tedious but worth it.
