Blips require a blip box to operate, so you’d need the blip switches, the blip box (controller), wires to connect the switches to the box which are sold in different lengths, front and rear derailleurs. Crank, cassette, and chain for the proper gears.
I guess you’d have to remove the shift cables from your brifters but the brakes would work fine.
I have Red eTap, don’t know the gen, but all of the parts came in separate boxes, ala cart.
