Is it possible to create a stand alone deb packages by merging dependancies without manual repacking.??

I've looked at this question but it doesn't really answer what I'm trying to achieve above.

if possible how to do it?

update 1

No tools available yet(?)
So what about creating new deb package containing all packages which will copy dependencies to the cache and executing main package.
Is it possible?

update 2

Above method appears to be impossible because dpkg cant handle more than one operation at a time. Some scripts may can do it

update 3

this tool is very helpful but it currently wont support oneric and above
still waiting for more generic tool

Thanks in advance
