Look at the screenshot that you posted. In each of the volumes, the blue is the used space and the white is the unused space.
A more ideal solution would be if you could shrink Workspace so that it had almost no unused space, and then grow Startup to use the extra space that Workspace just gave up. And then copy your data from Workspace to Startup, and then delete Worspace and grow Startup again.
But Workspace's data is in the way, the free space would be after the end of Workspace, not adjacent to Startup. It would require moving Workspace's data to the end of the drive, and I don't think Disk Utility will do operations like that that require moving data.
You can actually experiment to find out once you have your backups and before you delete the Workspace partition.
