From what I can see in the other discussion, you were preparing slides for TT Games about a product belonging to Universal to be merged with a product owned by The Lego Group.
From a business perspective that's a non-starter. You don't own either product, nor does TT Games. Lego is the core of The Lego Group, and Fast and The Furious is one of Universal's largest franchises. The best thing you can hope for is that they'll completely ignore your idea, and hope neither organization will send their legal teams after you. Creating and submitting a pitch on it is basically trying to sell something you don't own.
If you were to submit a pitch on it, you would need to submit the pitch to Lego or to Universal. You wouldn't present it to TT Games, nor would you present it here.
Since TT Games was acquired by Warner Brothers, a partnership there would be difficult, unless it comes with a few million dollars to make it easier on them. Both the proposal and the softening-up money would need to come from one of the two major companies having their products merged.
It is seldom seen publicly, but the major companies really do send out legal demands, C&D orders, and takedowns in response to pitches like you created. Usually those takedowns come with gag orders saying they promise not to sue into oblivion on condition of you removing every shred of it from the Internet and never speaking of it again.
