Creating package file from C#

Is there anything in webdeploy that would prevent me from taking a package file I have generated using msdeploy.exe -dest:package and opening that zip file using System.IO.Compression, modifying some attributes in the archive.xml saving it back and then using that package with msdeploy? 

I see attributes like MSDeploy.MSDeployProviderOptions and don't know if those might contain hashes of the XML data or something

Thanks
