Extending Seeded Projects Pages, LOVs

Question

Hi,
I would like some advice on what the best practice is for customizing the actual page layout in the OA Framework. We have a requirement to change an existing field (on a seeded page) from messageStyledText format to messageLovInput, i.e. making the field updateable and validated.
Should we be creating a new page, should we be overwriting the existing page, or is there a way of making this change as a personalization?
Also is there a way of substituting pages in the same way as you would substitute VO's as in the documentation?
Thanks,
Phil

Thanks for your reply Srini,
Our problem is that the page we'd like to change is a sub page of an AOL function. In this case: from the "Project Manager" Responsibility the AOL Function is "Project List", from there you select a project, then you select "Setup" then "Team Members" and finally "Update Team Member" (which is the page we would like to change)
Does that mean that we would have to change/extend all of the pages in the navigation?
The navigation from the "Team Members Page" to the "Update Team Member" page is done with a fireAction action type and not just a URI call. Is there a way to override that to call our New Update Page rather then replacing all the preceding pages?
Thanks,
Phil
