I wouldn't bet on it. Firstly, rust has value as a "C++ without the cruft" language even without safety as a USP, and secondly rust had to do a huge amount of design work to get the language to work in a way such that the kind of static analysis it does is reasonbaly feasible. C++ would need to adopt more paradigms and then create a subset of itself in order for this to work (there are such designs in the works like 'C++ Core', but they have already had to give up achieving the same level of safety as Rust gives).
