Don't know whether TLG ever considered to release a Product Line with models like this featured here today, but I believe it could turn into an interesting business case.
This is something different from the LEGO Technic theme, but still plenty of functionality/playability and a significant step ahead from the former Model Team or some modern Creator sets. They are actually designated 'crossover' models and a style used by many AFOLs and amateur builders.
The new PFS elements came to make creations like these, a lot easier.
With some nice stickers applied, this 6 PF motor mobile crane model from Co1Der (DoubleBrick, Russia) would turn into a very nice toy for the teens and above.
You may find additional photos at this BS folder (after moderation).
Meanwhile let me just recap some other constructions previously featured here at TBs , together with a few other models that would fit in the same conceptual range of products.
All these covering different set sizes, making an example how such hypothetical theme or product range, could look like into a given year lineup.
Most but not all of them motorized, these are models from M-longer, Han and Franzhe. Click over the pictures for more images about each of these.
For the high-end consumer range, also believe some like these (or slightly simplified versions in some cases - 6 motors may be a bit too much to make it affordable) would be feasible into a line of commercial sets, price and partcountwise.
I'm just still missing a good marketing name, for such crossover product line, but I can already imagining some appealing boxes on the shelves.
