With software raid this is no problem. Create the raid array using a
partition of the disk and not  the drive itself. This way when you get
a bigger disk you can partition and use the remaining space for
whatever you want (possibly using it in another raid array). I beleive
exactly what you are asking can be done easily with creating raid
arrays as partitions and using lvm to make these partitions look like
a single volume.
