PowerLoom and SUMO

I would like to construct a PowerLoom knowledge-base using ontologies 
constructed with SUO-KIF (http://suo.ieee.org/SUO/KIF/index.html).  My 
current plan is to create a tool that translates from SUO-KIF to 
PowerLoom KIF.  Note that SUO-KIF is a minimalistic implementation of 
KIF whereby many traditional KIF features have been moved out of the 
language with the intention of having them defined using ontologies 
(e.g.  defconcept, defrelation etc. don't exist in the language).  I 
could implement the translator such that it maps these concepts, or I 
can just account for keyword differences and load in the SUMO ontology 
with the requisite abstractions.  I'd prefer to do the later as it would 
be very simple to implement, but I'm concerned that I'll be missing out 
on some key PowerLoom features.  Are there any recommendations as to how 
I should proceed?

Cheers,
Cameron.
