Personally, and I've said this before, I'd like to see some cross pollination of the lines.

Make a few ML figures like Groot or other bigger characters but scaled to fit Marvel Universe. So their increased sized is covered under the Marvel Legends cost. This balances things out for the MU side and can also lead to repackagings like Giant Battle Packs or team packs or otherwise stipulated size differentiated packs.

Then this allows the Masterpiece side to cover both MU and ML with the characters that are just that much larger. It also opens the door still to do Marvel Legend Build a figures that can cover both MU and ML if they feel like it. Overall it'd greatly benefit the fans, there'd be more figure diversity and better height variance across all lines.

This especially works well for things like Groot, Ultron, Nimrod, and much much more.
They teased before with this using Iroman movie 1's Iron Monger that had the opening cockpit and again with the Norton Hulk movie line. Kind of sad to see they didn't take further advantage of it.

I'm kind of hoping the GOTG movie takes advantage of this principle though. The cosmic Marvel has the most varied sizes and body types and it'd be a perfect way to give us a new MU shelves Groot(Marvel legends sized and carded figure) as well as a Marvel Legends groot by giving us a slightly larger one for ML shelves with possible electronics that says his catch phrase.

That's just how I see it at least. The entire foresight with what can be made where and when to best monetize the properties and both please fans and help give children the heroes they love.
