Yeah, ESPs don't do 9 bit in hardware. At one point a while ago I attempted SoftwareSerial, but was never able to get it to work. Companies like Quark-Elec have been able to do it, and as I remember looking at their board it has an ESP there, but I didn't look at it in detail - there might have been an ATmega on the board as well.
I think your board is excellent as it is designed now. I'm sure you'll always find things you want to tweak!
It may have been asked before, but what was your plan for the current sensor on the board? The reason I'm asking is that I'm just in the process of replacing my batteries and rewiring power systems. I have shunts for current measurement now, but also have a couple clamp-on Hall Effect sensors I've been thinking about installing. Right now I have two equal banks - when I'm done I'll have a single big house bank and a starting battery. Both banks will need to be monitored. My sort of go-to process now is to program up an ESP32 (probably in the form of an M5StickC) to wirelessly send SK data to the PI.
