No. The vtable mangling is changed when vtable-thunks is enabled, period.
-frtti does not influence the format of the vtable.

In the traditional vtables, slot 0 has been reserved for the virtual
typeinfo function for quite a while now. -fno-rtti still reserves this
slot, but fills the typeinfo slot with a null pointer.
