Swamp Oil UOA experiment?

I was just thinking about how intensely scruitinized UOAs are around here, and I am honestly thinking someone could mix an incredibly diverse say, 20 quarts/litres of oil together in a five gallon bucket, mix them, run them in an engine and post a UOA, and the analysis would hardly be outside the statistical noise of any other UOA for that vehicle.

It'd be biased towards the synthetics due to the variety of grades, but I'd imagine 20 different brand quarts of SM 5W-30 would perform no better or worse on a scatter plot

Imagine a pail of:

- Joe Gibbs XP0 0W-5
- Royal Purple XPR 0W-10
- Fuchs Titan GT1 0W-20
- Amsoil SSO 0W-30
- Petro-Canada Duron-E 0W-40
- Eneos 0W-50

- Pennzoil 5W-20
- Quaker State 5W-30
- Renewable Lubricants Inc. 5W-40
- Castrol Syntec 5W-50

- Chevron Delo 400 10W
- Havoline 10W-30
- Castrol Magnatec 10W-40
- Silkolene Pro S 10W-50
- Shell Helix Ultra Racing 10W-60

- Shell Rotella T 15W-40
- Mobil 1 15W-50

- Valvoline 20W-20
- Castrol GTX 20W-50
- Motul 300V Le Mans 20W-60

- Accel SA 30

- Mystik Power Lubricants 40
- Penrite 40W-70

Besides being a pail of a variety of fully formulated, varied use automotive lubricants that would be ridiculously expensive...over the course of four oil changes in 20,000 miles, would that make a significant impact on an engine's life? (barring of course some additive incompatibility, etc. from the mix)
In a five quart oil change the Accel would only be about a third of an ounce...would it really make a difference?
