I kinda hope hasbro would consider the same with playsets. Think about it, interconnective playsets that work on a by room basis that become a shield helicarrier in scale when all connected over time. Like a BAF world I keep talking about.

There's no reason that it couldn't be done to be honest. Doll houses do it all the time.
Why not build an entire world like that? Sewers with street tops that interconnect, to rooms that build stark tower, or the X-mansion, or avengers mansion. Even the sentry tower. And even the shield helicarrier, or as others mentioned the millenium falcon by chunks. It'd lower the cost per item for greater sales, allow fans and kids alike to build there own desired one, and could cover the entire marvel or SW universe, even Joe universe ones in time.

It makes it financially feasible for fans and kids alike, increases play value, and creativity all at the same time. I know I've mentioned it before about playsets, but the idea very well could be adapted to the large scale vehicles too. Like the Flagg carrier, Shield Helicarrier, Millenium falcon, even the black bird. It also circumvents the toy safety laws a shade, since only each piece would have to pass. Not the full on vehicle.
Heck something like that could even work for a real to scale fortress maximus, or metroplex. To alleviate the store aspect, they could sell it online too, as well as assort the cases to an even divide over a length of time. Sure it may take a 3 years to build a full helicarrier, or flagg, or even MF, but it'd be worth it! Like I said before, if dollhouses can do it, why can't action figures?

Interactivity and universal adaption are also a must. That way if someone built let's say stark tower for example, but could never get the sentry tower pieces, they could use helicarrier ones, or the helicarrier could fit Millenium falcon ones, or stark's armory ones, etc. This way even if you're missing parts, you can still fit place holder ones till you find that part if ever. Making your world more you at the same time and less like everyone elses. It'd be a great way to revitalize the built to rule line.
