I think I’ll be better off finding 4 completely unused pins

You should read this thread:
Having seen your setup I really would suggest that you take a look at the Sonoff 4ch or 4ch Pro devices. They’re probably cheaper than the cost of the components you’re using and are DIN rail mounting, so lend themselves to neat modular installations and kale swapping-out modules very easy. They should be easy to re-programme to work with Blynk.
