Sorry to say it but good luck getting Lone Wolf Developement to work on ANYTHING that isn't Pathfinder related. I've been bugging them for HeroLab updates for BRP for years. Gave up.
Would make since to use Realm Works in this way, and actually, if you can speak the language, you could model your project around incorporating a BRP Data set into HeroLab, which may be easier. Again, if you can work with their authoring kits language...
They already have a decent start with CoC data set.
They already have permission from Chaosium for BRP projects BTW, so purchasing the authoring kit is all you'd need. (I think)
