well rsync is incremental, you could do an initial rsync during the
working week and do another to upgrade deltas during the weekend.

in this case you will have disks used up to 120Gb and an 80 gb of unused
space at the end. you could create another raid5 there, but it does not
seem appealing to me.

Really weird idea: please do not do it on real data.
You will probably shoot yourself doing this
- Switch the disks one by one.
- When you are over create a new raid5 over the existing one (keeping the
same settings for stripe size and parity algo)
- Resize the filesystem.
