Weight doesn't have nearly the impact that you seem to think.
Aero on the other hand. I have first world experience with an ultra aero dude on a TT bike fully optimized with the silly hat sitting in my draft and unable to pass me on my IGH touring bike with rack & fenders. On that 5 mile flat, straight, and windless path with good quality pavement I averaged 305 watts at ~23mph. He averaged 173 watts. He had every advantage and couldn't escape my rather large slipstream. I even pulled away a few times and let him catch up. I looked up his ride report on Strava. Turns out he was recovering from being sick & giving it his 100% At my power he would've cleaned my clock if he had it in him.
To be absolutely clear: He used ⅓ less power for the same speed.
Aero matters more.
