I dont think its possible but as I dont have much (read zero) experience with The Ken I never can be 100% sure.
But Jupiter templates are nothing more but settings of a theme. So you can recreate absolutely every Jupiter template from zero and using Jupiter default template. I assume its pretty much the same with The Ken.
We almost never use premade templates with Jupiter. I dont say that we havent got inspiration from them but there is actually no need to use templates as they give no new functionality nor design elements.
