It's not the worst thing to think that it may be possible. And relatively easy to use.
First things you would need to check tho are your ECU to make sure it's ethanol compatible as cars are generally tuned to certain blend be it regular unleaded or 98. If not you would need to look at and ECU set up that will option it.
The other thing you would need to have a look at is all of the fuel delivery and return lines. Plastic or rubber lines will get eaten through by the ethanol as will any regular rubber seals so they will also need to be changed if need be to be compatible.
Otherwise, ethanol blends are a much safer fuel for the economy in terms of oolution and similarly priced compared to 98Ron and They have better running temps so it's safer for higher power outputs as well.
I guess to start with 1 tank of a blend shouldn't do the car too much damage. I know a guy who blends a 90:10 98/E85 for track days on standard corsa B ECU without issues. But may see issues with a full ethanol blend in which case you'd just need to go and drain the tank.
