in principle I would expect so (provided it's not using persistent defaults), 
but there are probably complications - e.g. the way that PET uses reduced 
feature structures.  I think it would be OK, provided that you output the 
types without any defaults and the lexical entries (and rules etc) with all 
the default information included.  i.e., the use of defaults should be 
formally equivalent to a grammar where there is more information in the 
entries.

there's code that was used to dump out the lexical entries for PET and lilfes 
in io-general/outputsrc.lsp - I don't know whether it still works.

I've CC'd to Ben explicitly because he should be able to give you more 
detailed info about doing this.
