Of course it's possible in theory. But there are two aspects:

1) Do we really want to implement all PDF features? LZW is not the only
filter in the PDF specification that almost no-one uses. In fact, this
is the first time that I hear of someone needing LZW.

2) Manpower. Both ChoF and I are quite busy, so we would have essentially
no time to implement this feature in the near future.
