These will be compatible with the correct bushing also known as a template guide. I checked the description on Milwaukee's site and all it says is that it has an "4-point PM bushing", which is talking about the plunger, not the template guides. I didn't see it in the package contents. If it isn't there you may need to get a bushing that fits the jig plates. Milwaukee has a set that would have all the bushings you would need for this jig if you were to buy more plates for your jig. It runs around $40 on Amazon.
A typical spindle sander rotates at between 100 and 2,000 RPM, where a router is much faster 8,000 to 35,000 RPM. So I would say this is probably not the best idea, and could lead to damage to the equipment, injury, and death.
A laminate trimmer is pretty specialized and not a good choice for deeper wood working. A decent lockable plunge router can handle all the tasks you listed. I would invest in a good quality larger router as my first, more versatile tool.
