On the face of it, this all sounds a lot like the Mac works with .dmg images - it makes them mountable and then visible to the filesystem. No problem, if reading files is our goal. But if the OP wants to _boot_ off of them, we have a whole other kettle of fish. :-)
The quick and dirty way of doing this is to make a RAM disk the same size as the image (normally 800k for the IIgs), formatting it (to write the boot blocks), and then writing the 2mg file with DiskMaker to the RAM disk. This of course won't work with demos because they expect to run off a real 800k disk being controlled by the IWM chip.
