How to add free space to a Logical Volume Group? (Resizing Partitions)

I have two CoreStorage volumes on disk, one is 200GB the other is 50GB. I want to make the 1st 125GB and the second one 125GB.

Currently I have been able to use the diskutil cs resizeStack command to shrink my 200GB disk to 125GB. But am unable to expand my second CoreStorage volume to 125GB since its Logical Volume Group doesn't contain the free space I generated.

Then if we look at the df -k information:

If I try to resize the logicalVolume, or the Stack or the Disk they all get the same error:

~ james$ diskutil coreStorage resizeDisk F67F2DAA-2E8E-4AE7-A976-42230747BAB4 125G
Started CoreStorage operation
Error: -69771: The target disk is too small for this operation

So as far as I can figure, I need to add the space to Logical Volume Group 4793C4C8-0F56-4673-A2B6-98B15403CD33.

Any help would be greatly appreciated!
