I really want to go to heaven, and I'd hate to miss out just because I was raised Christian. Many different religions offer a path to some form of a better afterlife and require belief while alive in order to make it there, so what are the different religions that I can believe in concurrently in order to best ensure I have a good time when I die?

Additional info and background:

I'm looking for the most rationally effective method of hedging my bets on my salvation and ensuring my soul's journey to heaven, or at the very least minimizing its time spent in any sort of damnation or discomfort. Pascal is the most famous for attempting to solve this equation, but unfortunately he was pretty much only exposed to Christianity at the time and so saw the question framed as purely a binary difference between belief and non-belief.

Unfortunately I realize that there are many religions or interpretations of spirituality that claim that they are the exclusive path to eternal blessings and so Pascal's original solution of Catholicism is unsatisfying. Most forms of Christianity include that pesky clause of "You shall have no other gods before Me" (Exodus 20:3), and well, that means I only get one chance at being reunited with my heavenly host. I'm looking for as many religions as possible to believe in concurrently so as to maximize my chances.

I figure I have a number of bases covered with just living a good and moral life, as defined by trying to live selflessly enough while not infringing too much on my own productivity and happiness (so I don't have to give up all my worldly possessions and live a life of seclusion). Simply these actions get me to a bunch of different heavens or otherwise good next lives without me having to believe in them, which is great. This covers me under most forms of Judaism, Baha'i, Buddhism, Tengriism, Rastafari, and a bunch of others. Names of these religions are nice, but not essential.

I really only need to find those that mandate belief in them in order to make it to heaven and what I need to do to declare my intent to go; although quick guides as to what types of lifestyle changes I'd need to assume if required would be helpful as well. How many believers there are in this religion are not especially important for my calculations, nor does it matter how probable it is for it to be correct (I'm using Pascal's assumption within decision theory of an infinite utility for heaven and negative infinity for an afterlife outside of paradise, so the probability is actually pretty meaningless).

Also, for some religions it might even be alright that they decree a person must be a monotheist in order to be a believer, so long as that religion has some wiggle room for being imperfect. For example, though Pascal's Catholicism wouldn't let me believe in other gods and still get to Catholic heaven (due to idolatry being one of the mortal sins), most forms of Protestantism would see that as just another sin and I could still make it to Protestant heaven provided that I become friends with Jesus. But please make mention of any of these caveats so that I can be aware ahead of time!
