Convert PCP to MSP

QUICK ANSWER
Is it possible to convert PCP to MSP?
Yes - PCP converts to MSP.

The whole purpose of a PCP: run it through Msimsp.exe (PatchWiz.dll) to GENERATE the .msp patch package. This isn't a file-format conversion - it's a build step that diffs target vs upgraded MSIs and emits the patch. Command: Msimsp.exe -s patch.pcp -p patch.msp.
