Customize Visualforce pages in a managed package extension

Hello,

We are developing an extension package that works with a base package. The base package has visualforce pages. We are adding additional fields in the extension package and need to include these fields in the existing visualforce pages of the base package. I cannot edit the visualforce pages from the managed package in the extension package development org.

My question is do I clone the VF page, add the fields in the page and package the pages in the extension org or is there any other way to do it? I will then have to install the base pkg, install the ext pkg and update the link/configure the org to use the new ext pkg VF page link and discard the base pkg VF page?

Is my assumption correct? Can someone help me verify?
What are some of the best practices/limitations of using VF pages in managed packages?
