Knowledge Advanced content can be indexed in Knowledge Foundation?

Content

Hello Experts,

  As per our PoC use case , need to index the KA content in KF (External search configuration) to get the specific content type answers on KF customer Portal.

Now I want to know the feasibility of this and what can be the Pros and Cons  ? I know Knowledge Advanced has quite good indexing mechanism but not sure about KF.

Thanks in Advance.

Regards,
