Gorlak: I have CS5. These things used to have good backwards compatibility, so if you have other version it shouldn't be much of a problem.
As for BFG:R rules - glad you'd like to include them. Of course, they'll need to be clearly marked as belonging in BFG:R.
Heavy escorts are not a problem - without relevant position in the fleet list, their rules don't do anything as no old list has any 2 hit escort ship.
Nova cannons would require some sort of 'alternate rule' frame. Or just place both rules in the appendix at the end as it has been said, to make it easier for folks not accepting the revision. (When one day everyone will embrace BFG:R's light, we'll make a new version with rules in place
)
also, found one more thing: beginning of the Ordnance Phase chapter, 2nd line - sucll instead of such.
