I don't know if 5e uses the same D20 attribute bonuses but what I did in D20 was to give the players a certain number of total bonus points. So they may start with +12. They assign those to the attributes. Then roll a single d6. If it is odd then the first attribute number will be odd. Look up that attribute bonus and take the attribute rating that is odd for that bonus. The next attribute will be even and alternates all the rest.
It is SOOOOO much faster and it gives the players a lot more control. You can set the total bonus based on whatever you want them to average to. You could have +16 for truly powerful characters or +5 for normal modern characters.
