What are your dream Metal Gear franchise crossovers?

[Dirty Duck]

I really enjoyed Snake, Big Boss, and Raiden appearing in Super Bomberman R as free DLC but I'd like to see Fatman in a Bomberman game with a stage based on the area his fight takes place on the Big Shell. I just feel like he'd fit in very well with the Bomberman aesthetic and his roller skates and bombs mean he has the perfect set of abilities for the gameplay anyway.

I'd like to see an MGS crossover in a Worms game that adds some of the weapons and items the series is famous for-Cardboard Box, FAMAS, NIKITA, MK22, Moisin Nagant, SOCOM, Claymore, Fulton, Magazine, HF Blade, Rocket Punch. A Shadow Moses and Big Shell level style would be fun too.

I've wanted MGS2 Raiden in Smash as an echo fighter of Snake for ages too. Slight variations like his smash attacks being his HF Blade, his dash attack being his cartwheel, his down special being coolant (that can freeze enemies as well as Snake's C4, preventing him from detonating it and disabling the move for a while), Stinger instead of NIKITA as his side special, which would lock on and be faster moving but be less powerful. Stun Grenades instead of hand grenades, which put the enemy to sleep for a small amount of time.
