I've never had a crash due to following the described procedure. I do it all the time on Free Roams I've created, having loaded them down very heavily with DLC placed all over the route, in addition to scenery object additions. The scenarios are on high density urban routes, e.g. Hamburg-Hanover and Northeast Corridor Phila.>NY, an exception being Sherman Hill. Although, the more I keep playing with SH in the editors, the denser it gets. I think it's called Bob Artim Syndrome (
"I don't know how to stop, I give it all I got...")
The worst result I've experienced is a little slow down in frame rates on H-H in the vicinity of Hamburg and the large yards. But never a crash.
I will admit the sim at times has looked like it was about to toss its cookies while loading all the goodies at one or two newly selected locations while in the World Editor, but so far it's kept them down.
As we know, computers and computer specs. have a good deal to do with variations in personal experience with this sim.
