No, not without some severe hardware hacking. The IIgs uses NTSC or PAL 
scan rates for its RGB monitor, and the frequencies are well below what 
Mac monitors used (the 14" used the old Mac-standard 640x480@67Hz 
timings, and only those timings -- back then, multiscan monitors were 
still rare and expensive birds).

As for other monitors that will work, the pickings now are somewhat 
slim; the last CRT multiscans that supported analog RGB at the 
frequencies a IIgs uses were made over a decade ago. If you can find a 
working one, a pre-FG series NEC MultiSync (like the II or the 3D) will 
work, as will some of the older Sony multiscans (1302, 1303 and 1402 
according to Griffin's database). There are also a few old color 
monitors (made by Magnavox and Amdek, among others; Commodore also sold 
one) that will take analog RGB as well as TTL RGB (CGA) and composite; I 
have a Magnavox with that feature on my IIc+, though only as analog 
since the DIN connector for analog RGB isn't fitted.

Keep in mind that these are all very old models now, and will be 
somewhat difficult to find in good condition.

There are also scan doublers that will let you use a NTSC or PAL 
composite input on a regular VGA monitor, but I understand the quality 
leaves something to be desired, and I haven't seen one that will do 
analog RGB input yet. You can also use a LCD projector to do it, but 
they're still quite expensive, and would be somewhat like killing a fly 
with a wrecking ball in this case.
