I don't really understand your question....

It usually doesn't make sense to split a disk in smaller partitions and
RAID them togheter. If the whole disk dies, you loose two partitions and
your whole RAID-array.

The software raid implementation in linux doesn't allow you to add more
disks to an existing array, but of course you can delete your array and
create a new one with more disks. Some hardware raid implementations
(and possible some software-raid implementations too) allow you to add
more drives without redoing the array.
