Thoughts on Hacking 5e subclasses

It seems to me that the best way to approach this is to look categorize the classes by their core and secondary stats. The classes that share a core state should be able to easily swap out subclass features
I’m going to call this a Synthesis Build
When a Synthesis levels up, they must choose which sub features to take. they cannot take both.
