Technically speaking, you should be able to manage if you use "page" 
writes of 16 bytes instead of attempting to try and write 1 byte at a 
time. You will need to store a page of 16 data bytes on your PIC while 
the 24xx chip is writing.

Is this something you plan on doing long term?
Reason asking is that the part is specified reliable for about 100,000 
writes, which comes out to about a very short 15 minutes of use:

100,000 x 16 x 600uS = 960 Seconds worth of "reliable" use.
