Yes it is possible. Strangely enough, this is no longer documented but you can find it in the FBX 5.2 documentation, albeit poorly described. I did it here for a whole bunch of mo-cap, which would have been a huge pain otherwise.
The command you are looking for is "FBX import".
Unfortunately, I found that you have to go through a few steps to get this to work, seeing as the batch importing only works when the Exclusive Merge option is turned on. But in order to do this, you need a Model of the target geometry already in your scene to merge it to.
The script we wrote imports each FBS file and converts it to an action source.
Anyway, let me know how it goes. If you have too much trouble, I may be able to help out.

Hi everybody!
Does anybody know if it is possible to access the Kaydara FBX import
options through scripting, enabling me to batch-process a folder full of
them in XSI? The fbximport command itself gets logged with two NULL
arguments, but they are not documented. Could anyone of them perhaps be
used to pipe in the fbx file name?
Cheers!
