This should work.  The VIPER 150 can read both 150 and 60 MB tapes
(I *have* tried this), but indeed only write the 150 MBs.  The dual
config should work, especially if you use the wangtek or archive
with its own controller, as this uses a different driver, different
major device number, and different /dev entry names.  I can't vouch 
for how running two SCSI tapes work, although theoretically that too
should work, just as long as you assign different SCSI IDs.  Let
us know what you find out.
