For this, isn’t it sufficient to measure the corners of your speakers relative to the wall (e.g. left front and right back of each)?
In case they’re the same left to right, you should be good to go. This also works when toed in, IMO.

Great room
Yes, exactly what I’m doing now. But I’m lazy and with all new laser meters and levels I was hoping for something easier, able to let me do adjustments on the go based on a red light projected.
For instance, having the center of the room fixed on one point on the floor, I’d like a projected laser both on the line from front wall to the listening position AND on the perpendicular line, the axes of the front baffles of the speakers. Like two laser walls projected from their intersection axe.
Luca , to adjust the Toe In/Out of my speakers I use a little hand held laser pointer. Something like this .
I centre it on top of the speakers pointing back to the listening position.

Lazy? What about that brain power involved to come up with such solutions!
Well, in case this is just a temporary requirement (highly doubtful amongst Audiofiles), you may hire such equipment from a contractor, or a contractor’s supplier. Then do expect to meet raised eyebrows, explaining how many and why exactly you need those for.
And warn your wife they may be dusty.

I’m using this one actually
It might be enough (with a little bit of patience).
