How do I combine 2 ASM diskgroups?

I inherited an Oracle 11gr2 RAC Database running on Windows  that has two ASM groups that really should only be one.  There is a +DATA diskgroup and also a +DATA01 diskgroup.  And both of these DGs have inconsistent LUN sizes.  I have found out that the second DG was created when the previous DBA had trouble adding a new LUN to the existing DG.  Not sure of the details - it is what it is.  The first task that I am going to tackle is getting the LUN sizes consistent across each diskgroup, and that shouldn't be an issue.

However, I really would like to have only one +DATA DG.  Is there a way to combine these 2 DGs?   I would even be okay with a third name as long as both +DATA and +DATA01 could be combined to form the new DG.
