Actually, if you format your USB stick to NTFS, this should work. I 
remember to have had a mobile cygwin stick around a while ago.

Having trouble following the assertions here.
I've had a FAT32 portable USB stick supporting both Cygwin32 and Cygwin64
for, dunno, 20 years or something. I made a new one from scratch last night, actually,
absolutely coincidentally to this post. Whilst not "Full" the installation is way in advance
of "Base". I just run
setup -P <list of packages I want - exactly 50 of them>
at the Windows command prompt, installing to a formatted FAT32 stick, and away I go.
Time after time after time.
