ChIPseeker has plotAvgProf() that will make a profile plot of a certain distance from a single point. Is there something similar for gene body profiles? It's a similar idea, but instead of a single point, it's a variable length region in the middle, so you have to normalize for length.

Here is an example of both types of plots in case I am not clear:

this is a good idea. I will consider to support it in future release.
