I'd build a board, it's fairly trivial.  Compared to the mods needed to 
make a 2708 board take 2732s.  There is one easy way and thats to make 
a header that takes the 2732 and maps the Data/Address/CS-/OE- pins 
to the 2708 socket along with power and ground.  That will allow only 
using 1k of the 2732 but that may be all you need.  the upside is one
2732 can hole 4 1k programs and it's easier to program than 2708.
