If you were going to do that then you would have to add a lot of randomness to which move you do. Obviously you can't just raise every hand, barrel every turn etc. You would have to consider your own range and think about how likely you would be to do each action with that range. This could derinately be an interesting excersise in thinking about what you represent now what you have. Your own hand is just one of many factors, of course.
With that said, I can assure you that It's better to play while looking a your cards. If you get to the river and are faced with a bet, knowing your range won't completely tell you whether it's a good call- you need to know your own hand! It is far from true to say that your own hand is not important and I can assure you that a player who never looks at their cards is highly exploitable, and could end up making a huge fool of themselves.
Maybe try it for fun/ studying the concept but don't expect to be as profitable (there might still be really poor tables where you can still make a profit without your own cards).
Good luck!
