The US Census Bureau defines a "Baby Boomer" as someone born between 1946 and 1964.
Extending that to aircraft, and translating "born" to "first flown" - it's an era that encompasses some of the greatest advances yet. So, how about a Baby Boomers build to encompass both the last of the piston-engined aircraft and both the 2nd (and 3rd) generation jet- and rocket-engined successors.
We're talking the final versions of WW2 workhorses, through to the XB-70 Valkirie and TSR-2 - and all that went between.
Build timescale? Knowing my reputation, sometime next year at the earliest!

All the best
