possible but very unlikely. our decline will likely slow somewhat and populations will stabilize after members with genetic predispositions to religiosity and outgroup altruism have been significantly weaned out, so that high fertility white subgroups are the majority of whites. but western countries will be like 85-95% brown by then, with the remaining whites heavily mixed (dating options for fertile women will be less white each generation and the temptation to avoid your own low status group might be high) with the new brown majority very keen on killing us. expect our already high suicide rates and drug use to climb higher in between then and now.
