I could use an external drive rack, build a RAID array, and use it to
replace my primary tapepool, correct? What would be the disadvantages of
that vs. a VTL? 

TIA

That's what we are doing. Our primary is a 6.4 TB VTL.
So far, it's working very well. Excellent performance.

Main concern is if the device fails, how long will it 
take to restore all those terabytes of primary storage
from offsite volumes.

Our IBM 3583 tape lib is out of space. 

What do you think of this idea?

Acquire disk-based appliance i.e. 3 TB. Use it for primary. Use 3583 for
off site tapes only.

Please advise.
