Even assuming your mushrooms contained this extra non-scheduled alkaloid, I would still imagine that there would be a fair amount of psilocybin and some psilocin in there as well as the mushroom probably wouldn't exclusively produce this 4-OH-5-MeO-DMT. Now having said all of that, I remember a discussion a while ago that talked about including DMT in growth medium of plants and it was concluded that it probably wouldn't make a difference (but that was for plants and this is for fungi, so perhaps the mechanism for the assimilating the alkaloids would be different). I can't give you an exact answer, but I would wager my bet on that it wouldn't happen at all, but I'm wishing you the best of luck. I'm actually rooting for you. If it is possible, it probably isn't legal, but it would be cool if you did it anyway

Also where did you read that?
[Edit]: Also we know that 5-MeO DMT is orally active as is psilocybin and psilocin obviously, but would this novel tryptamine you read about even be orally active?
