I am thinking of adding an average house edge for every sportsbook. That way, we can compare which sportsbook gives the best odds in general. It's going to take a lot of time and data(and calculation) to get accurate average for a specific sportsbook. Should I venture into it? or just let it be? anything else that one would like to know?

PS: I know a lot of sportsbooks give bet boosts for popular events which will make things tricky.
