Hi Andy,
Without meaning to be rude in any way, I would recommend against the plan as you just laid it out. This is for a couple reasons.
First is that walking around in the dark through a night-vision monocular attached to headgear is actually remarkably challenging. Good ones which have wide enough field of views and good enough brightness compensation that you can get an idea both of things at distance and things right in front of your feet tend not to come cheap. It also can cause a lot of people to become motion sick, because your visual inputs become messed-up compared to what your inner ear is perceiving. Furthermore, even if you got such a monocular, you'd likely have a hard time using its relatively low magnification to actually get a good point of aim on fleeting targets with a laser designator. They just don't gel well together.
What I would recommend doing is one of two paths:
1) A monocular with higher magnification mounted directly to your rifle. Some come with options for lasers, others come with reticles. You might be surprised at how cheaply they can be had these days.
2) purchasing one of the night-vision-through-scope rigs. This uses your existing scope with its existing zero and simply looks down it. These days they can be had quite cheaply. Your springer may or may not have too much recoil for one of these setups, I've never tried, but it is worth considering.
I should note, I actually posted a review on a couple budget night vision optics a while back. Maybe you'd find it helpful?
