Like till it gets closer we dont even know if it would be suitable to put something like that on it.

Although it does seem like interesting idea.

However, we have sent probes much further than this object (aka the voyager missions).

So it would mainly be useful for studying this object. So a telescope would be less than ideal since we could always in theory deploy a telescope much deeper into space if we wanted.

Interestingly, the voyager missions were also timed-events -- they were launched when they were because JPL realized it was a 1-in-175-year alignment of the outer planets that made it feasible to launch just a few crafts to visit the outer planets all in one go: https://en.wikipedia.org/wiki/Grand_Tour_program

AFAIK many launches are timed to make the flight shorter. Although not on 1 in 175 years, but shorter windows.
