Good morning Alf,
You can use the "Search" feature on this site to find information and there's a lot of it regarding inverted systems. Many have been installed in RV's of all models.
It makes a tight fit since there is not much extra room between the engine and firewall. The system adds extra weight and complexity as well. You should also have inverted fuel capability if you go with the Christen system since it sounds like you're going to do a lot of inverted flight.
Personally, I'd prefer to keep the airplane light and nimble because you can do most maneuvers without pulling negative G's. Only slow rolls and inverted flight will you have negative G's. Cuban eights, four point rolls, aileron rolls and Immelmans, loops and split esses can all be done without going negative.
Regards,
