Well… for retinoids it can take up to 6 weeks before you see any form of irritation (flakiness, dryness).
This one from TO is the one I prefer best based of Dr Michelle from Lab Muffin Recommendation as the more photostable retinoid of TO.
I actually use retinoids almost every night except when I am lazy. I keep dryness and flakiness at bay my using the moisturizer sandwich method. Moisturizer retinoid moisturizer.
Back when I had oily skin, retinoid was the thing that kept my skin not oily.
When I use retinoids at night I avoid using Vit C, AHA and BHA. If I understand what you mean that means you want to alternate AHA and Retinoids every other night? if so then I think it should be okay. Just listen to your skin if there is irritation and you can skip a day or two between them.
