That would mean doubling the potential admittance (which we already is not even remotely feasible).
Beaides, if you are travelling with a +1, you can always go in the MLL.
It's not doubling it depending on how they do it.
If the +1 must be in J on the same flight, then that means they're in R or I class. Confirmed in advance.
And if it's limited to ONE guest, there shouldn't be a huge increase.
This would basically just solve the "I bought a ticket and redeemed points/upgrades for my significant other" problem.
Would that cause overcrowding? Maybe. Nice way to take someone for a fancy-ish dinner before a flight.
But it's limited to the lesser of paid seats and seats released for miles/upgrades, which is completely controlled by AC.
