I don't know.... ........maybe I'm more positive.
On my laser you can pull the last mirror off and set a jigged red dot pointed.
Shoot a test beam to establish a "sweet spot"
replace mirror with jig.
then adjust the pointer to hit the spot
replace back to the mirror and then lase.
could work great...!

Just because I doubted myself I decided to find the answer.
"The law of reflection states that the angle of incidence equals the angle of reflection."
In other words, the angle the light hits the mirror is the same angle it is reflected. If you have two beams of light that are from two different sources, they can't possibly hit the mirror at the same angle so they can't reflect to the same spot either. Same thing when playing pool, the angle your ball hits the rail is the same angle it bounces (barring english, defective rails, etc.).
If you want a detailed explanation go to the link below and you can read all about reflective light and angles of incidence and refraction.

Not knowing the style of mirror/lens assembly on your machine, If you put the laser light in the opening, won't that block the Laser Beam? or worse.... burn up the laser pointer? :/

When I first went to align my system I was surprised. It did not matter at what point of the mirror the beam hit, the spot was in the same place. The lens does that.
If the beam is entering at a very different angle it might, (might), make a difference, not sure.
