Like I said I would not run 20W-50 in a daily/street driven DSM personally. I run 5W-30 in mine, and mines a summer only driven street car here. If you're concerned about the higher temps, then like I said consider going up to say a 5W-40 or 10W-40. If you're really wanting to make a science experiment out of it, get an oil temp gauge as that will be the best tool to tell you what weight to get for your application.

Remember that your oil doesn't even get to operating temp until you've been driving say 20-30 minutes under normal conditions. So if you're just taking 20-30 minute trips, your oil is barely even making it to it's operating weight anyway.

Sounds good to me and not trying to make anything more difficult.

I couldn't agree more. Your coolant gets up to temp about 10 miles before your oil will. My current commute is 7 miles one-way and the coolant is up to full temp after about 2 (210-220F), but the oil never gets there (full temp on my oil is 220-230F). The C7 Z51 holds 10 quarts, but it does have a heat exchanger that warms the oil with hot coolant.
