For a few years I used a 602 in 458 Win and I hated that arse about face safety catch!

I'm very used to the standard pattern of push forward to fire push rearward to put on safe.
My shotguns, double rifles, and all my other bolt guns use that standard pattern, so having one that was back to front was a real pain.
If I was forced to own and use another big Brno for anything serious, I'd definately want to somehow change the direction in which the safety catch operates.
I'd be looking to the mod 70 modification or I'd attempt to alter the original safety if that was possible.

I fixed my 602 safety issue by selling it and replacing it with a double fitted with standard tang safety working in the proper direction!
