I like that idea!

Probably the only really big innovations since the 1970s in camera and lens design would be matrix metering and image stabilization.

Improvements in wideangle and zoom lens design for 35mm cameras since the 1970s are significant, but might best be regarded as tweaks or the innovations in high-end cine and video lenses filtering down to consumer still cameras, rather than anything revolutionary.

Canon made that diffractive optics lens, which is probably no better than my FD 400/4.5 SSC except for image stabilization, but maybe that might lead to something genuinely interesting in the future.
