Would it he good for the NDP to adopt a policy of straight up socialism?

The federal NDP is struggling right now. What if they were to say, “yenno, fuck it, we’re straight up 100% socialist. Our platform is now that there can be no private ownership of the means of production, all workplaces are democratically run, etc.”? Would this help revitalize the party, or would it cause people to distance themselves even more? What is the state of public opinion on this right now, in your assessment?
