I imagine it can only help, more surface area should mean more stregnth along layer lines.
I'm also thinking about the fiber core filaments that are out there, straight polymer at the layer joins should be stronger than traditional fiber infused filaments. You probably don't get the same aesthetics as typical CF filaments though.
Another stregnth related area I'm exploring is electron beam treatment. It's used in other areas with plastics to change/improve the base properties, and it's even used in a PLA variant common in medical devices to improve performance there.
It can turn thermoplastic into thermoset plastic, it creates longer polymer chains in otherwise finished products.
If it can be applied to prints it may greatly improve overall strength durability and temperature resistance, but more to my point, it might drastically improve layer line adhesion.
