9 years ago plot_topo uses a Layout object that defines the drawing position of the channels. The simplest way to achieve what you describe is to write your own layout file. Usually, you use the same recording setup over and over again, so investing an hour or so in creating your own custom layout is worth it.
If there is a pressing need to be able to do this in code, I suggest adding it to the make_eeg_layout or generate_2d_layout functions.

For the plot_topo functions it would be nice if the picks argument can take multiple channel groups Eg: picks = [[1,2,3],[4,5,6]]. The plots can be shown at the centroid of the channels within a group. This can reduce the need to plot all channels resulting in really small plots for data recorded with a high density channel system.
