Can a Google Voice number be daisy chained to another Google Voice number

You will need to fill out the Troubleshooter for Account Transfer.

Once this transfer is initiated, it may DELETE ALL OF YOUR SUBSCRIBER INFORMATION, on your destination Google Voice account, like your call history, text messages, and voicemails. Your contacts will NOT be migrated however, they will be preserved for both accounts.

The process may take up to five (5) business days after which they will email you the outcome.

It will be easier if the new Google Account does not have a Google Voice number.

Yes, you should be able to change your number, like this, but there's a $10 fee. If you contact their support, perhaps they can arrange for you to "swap" the numbers the way you want. I don't think there's a way to do this yourself, without contact customer service.

As an alternative solution, I would suggest checking out Skype. I believe they offer the same kind of services with a bit more "flexibility" and with some additional features.
