I'm not saying to _not_ try it. It's just going to be a dumpster-fire-money-pit that has an extremely high probability of either bankrupting you or producing nothing of significant value. This isn't a shot at OP. The best way to force change here isn't yet another journal, but rather fix the access issues of current journals, convince them it's a good idea to be less exclusive (ever noticed certain initials tend to be published more than others?), and moreover stop the university-journal death-bond that currently is in the market.

Good luck at any rate.
