New VO to substitute an existiting seeded VO wo extending the seeded VO

Question

Hello All,
Is it possible to deploy a new VO by substituting the existing VO without extending the existing VO.
==========
I mean,
There is seeded VO pointing to couple of seeded EO's. Now I want to extend this VO but want to completely replace existing EOs with the custom EO's. But when I try to extend it , I am unable to get rid of the old EO's to replace it to the new ones! By extending, Jdeveloper allows me to add more EO's to the list but dosnt allow me to get rid of the existing EO's.
I tried creating a brand new VO with the custom EO but this errors with "all variables not bound"! error.
The seeded EO and the Custom EO will fetch the same result set but from different source (from custom EO).
=========
Having said this, Is it possible to deploy a new VO by substituting the existing VO without extending the existing VO.
Thanks for all the help.

Ramkumar,
This is what I am trying to accomplish...
===============
E.g., The seeded VO has the following SQL query ...
select ppf.first_name, ppf.last_name, ppf.national_identifier
from per_all_people_f ppf
where ppf.person_id = :1
and sysdate between ppf.effective_start_date and ppf.effective_end_date
==============
And I need to change this query to ...
select xmp.first_name, xmp.last_name, xmp.national_identifier
from xxc_my_people_v xmp
where xmp.person_id = :1
and sysdate between xmp.effective_start_date and xmp.effective_end_date
=============
When I try to extend the seeded VO, I am only able to add more to the FROM clause in the form of EO's. (Only thw WHERE clause is editable)
====
But when I create a new VO as you are suggesting, I get an error when using it after the deployment "Not all variables bound! ". There is only one bind reference in the original VO query and am using the same reference in the new expert mode VO that I created!
=============
Please let me know what I am missing.
Thanks for your help!
