If I'm reading this right, upx.exe is getting used at build time to compress the file but the compressed file will then get stuffed into a cab anyway (because that's what Windows Installer requires). Perhaps MakeMSI is not compressing the cab and using it strictly as a container.
You could simulate this by updating your build process to call upx.exe for the appropriate files at build time (some time before you call light.exe) and then specify that the Media (cab) not use compression (double compression typically results in more disk space consumption). You'll need to decompress the files after they are installed with a custom action. Supporting something like this in WiX should not be impossible but I think it will be highly unlikely to be supported as this will require a custom action to decompress the files after they are installed.
