There are two RAM disks here:  The /RAM I mentioned earlier is the ~64K
one that ProDOS 8 provides (using auxmem).

The IIgs RAM5 disk always has a size that's a multiple of 32K.  It would
be possible for a RAM5 driver to make it show up as a different size, but
the driver included with System 6.0.1 does not do that.  (At least 800K
is a multiple of 32K, so you can unpack 800K disks to RAM5, or do
whole-disk copies in the Finder.)

Also, the A2.RAM.Card ("Slinky") driver in 6.0.1 lets you call a 1024K
card an 800K disk.

None of which helps you unpack to a 140K disk.  Maybe you can get
somebody to write a "RAM140" driver.  It would be pretty easy for anybody
who has already written a GS/OS device driver & has some time.
