Xbox, just starting off, weird question

I’m currently finishing up my yearly survival permadeath run in Fallout 4, randomly found out you can become a ghoul in 76 but you have to be level 50 to do it. I’ve always wanted to play as a ghoul but I was just wondering about how long it would take to reach level 50? Sorry if this is dumb, just seeing if it’s worth trying to grind or if I should just download mods for 4. Thanks in advance to anyone who responds.
