I would suggest actually practicing according to the Visuddhimagga and going through the stages of insight. As far as I know, one must first practice the four elements meditation and see ultimate reality before he can practice vipassana.
If someone practiced according to the Visuddhimagga and has learned the vipasanna sections, I think it’s possible to attain stream entry before one dies or in the deva or brahma world unless he aspires for supreme enlightenment (Buddhahood) or any kind of enlightenment that requires him to fulfill paramis for more lives.
I hope you achieve your heart’s desire. I do think it’s still possible to attain jhanas, psychic powers, and enlightenment in modern times. We just have to put in every ounce of energy we have and trust in ourselves, the Visuddhimagga, and our teachers who will teach us.
