Can the install floppy data go on a flash drive?

This may sound a little odd but I was wondering if there is a way I can 
get the data from the 5.2.1 install floppies onto a flash drive and boot 
the install process from the flash drive.

The machine in question does not have a floppy or CD-ROM drive so my 
options are:
1) temporarilly connect a floppy drive
2) Figure out how to get PXE to work for an install process
3) Some other option yet to be determined

Any ideas?
Google turned up some stuff but nothing about building install images 
(that I could find.)
TIA...
