[Suggestion] Optimize for stacked boat and minecart

We usually use stacked boat as elytra launcher, and use 24 minecart to execute mobs. But it cause huge lag on server…

Is it a good idea to merge them to one entity in server, but keep it’s function?
The merged boat can accelerate entities to high speed based on how many boats it stacked, the merged minecart can cause suffocation damage to entities in it.

Or is there any plugin can do that?
