Depends on whether Fallout 4 is a Fallout:NV successor or a Fallout 3 successor.
As an element of Fallout:NV++, this is somewhere between ‘absurdly suitable’ and ‘overtly mandatory’. As an element of the grittier, more urban, east-coast flavor of Fallout 3, it would be OK as an easter egg; but thematically dubious.
