Yes, it is possible.  Your XT hard disk controller will support up
to two devices.

Remember that there are two cables between the hard disks and their
controller.  One is buss-wired and must attach to both drives.  The
other is a separate cable per drive.  It might be easier to put both
hard disks in the external enclosure, or to use two half-height
devices in your XT system unit.  When you run the ribbon cables from
your system unit to the external enclosure, you'll probably be
building a system that will be non-compliant with FCC part 15 (RF
emissions).

There are several external drive enclosures on the market.  I use
one from Walker Electronics of somewhere in Texas.  It has room for
two full-height devices, and contains a power supply capable of
handling two hard disks.  I have a 67 Mbyte Miniscribe and a 40
Mbyte Tandon connected to an AT&T 6300PLUS running UNIX/DOS.  There
are two diskette drives in the system unit.
