oh, it's totally do-able.
http://blog.kihltech.com/2012/12/sata-hotswap-drive-in-mdadm-raid-array/
for an example. i'd argue it's even easier to do with mdadm than it is
with most dedicated RAID controllers.

note that you can even hotswap non-raided devices with newer SATA
controllers, even consumer level (provided you aren't running, say,
/usr on the disk you swap out. there are ways to do that, but if you
need that kind of hotswap capability- you're gonna want to run a
mirroring-type RAID regardless).
