To placard your panel in lieu of an AOA indicator, you'd have to have a multi-dimensional lookup table with at least bank angle, weight, CG location, and you'd have to cross-reference several instruments with that table to know at what speed your plane will stall. A common stall/spin LOC scenario is pulling too hard of a bank to compensate for overshooting final. I very much doubt you'll take the time to figure out your stall speed in that scenario, but an AOA indicator can let you know how much margin you have at a glance.
You may or may not find that AOA information is necessary or useful the way you fly your airplane, but making a table is definitely not the same thing as having a calibrated AOA indicator.
