Failed Data drive, single parity drive. Replace with large size drives

I currently have a failed drive that I probably could bring back online by ignoring whatever number triggered the failure count.  But baring that for a hot moment, all the drives I have are currently 2TB drives.  I want to start replacing them with 4TB drives.  I know I can't (specially at the moment) just take out the parity drive with a 4TB drive because of the failure and i can't put the 4tb in for the failed 2tb data.

 

Could I add an additional 4TB parity drive, leaving the 2TB parity drive.  Once the array is back up and 'stable', replace the failed 2TB drive with a new 4tb drive?   

 

Or is there a way I can make this change work?  I don't have anymore 2TB drives left floating about.  I didn't wanna buy another 2TB drive when replace all of them with larger drives anyways.
