Beautiful set up. Not only are you not married, but with that much around I'm guessing you don't have any little ones running around? My 6 year old is a terror and constantly tries to find ways into my cabinets.
As a Kitbuilder I'd say get there are only two reasons to fix the cracks. One, its bugging you (I mean REALLY bugging you); and two, if they take any of the weight of the figure they can get worse as time goes on. I pin EVERYTHING I can on my figures for that very reason. These don't look like weight points, but its hard to tell.
That being said, make darn sure the person you turn it over to knows what they are doing. Even a good repair/kitbuilder can fudge something up and your risking your entire statue. Better a small crack than a bad repair job.
In fact, if you can live with the shame
I'd leave them alone unless they are going to get worse.
Also, did you collect all those this year? Or did you collect before and now just bs with the forum? I'd have to sell a kid or two to get that kind of collection in one year . . . oh, and get divorced. Hmmmmmm.
As I said initially, beautiful setup.
