Is there a way to increase "max post length" for a specific topic?

Is there any chance that one could set the max post length for a specific topic (or a user/token who is sending the body of the topic)?

You could create a plugin that would let you set the max post length to what you want for the one topic (or user?) and then apply a different one for the rest.

Why not just increase the post length for all posts?
