checking in a cvs working copy to subversion

Hello,

I have code from an open source project in a cvs repository.

I would like to use subversion version control on a new project based on the
source code from the open source project mentioned above.

I would like to be able to get updates from the cvs repository of the open
source project as much as possible and contriubte code back to this cvs
repository, the problem is that I am using subversion.

My initial idea was to checkout a cvs working copy from the open source
project repository and check this in to my subversion repository. Yes
everything including the CVS directories.

So I checked out a working copy from my personal subversion repository.
On this working copy I would occassionally do a cvs update to retrieve updates
from the cvs repository of the open source project and then svn commit.

Will this work or is this a recipe for disaster ?

Suggestions, comments and thoughts are most welcome.
