Legacy boot on GPT has some requirements, but it works

but we are talking about a LIVE-migration/reshape of existing disks with 
no place left for another partition

So what ? Aren't you going to create a GPT partition table on your 4-TB 
drives ? Else you won't be able to use the space beyond 2 TiB. (*)
A GPT partition table supports up to 128 partitions by default.

(*) In the DOS/MBR partition scheme, Linux supports that a partition 
ends beyond 2 TiB up to 4 TiB but this is a non standard trick and 
probably not supported by usual partitioning tools.
