No. You have a choice between size for files and directories ("size" in
the "Listing mode" dialog) and size for files only ("bsize" in the same
dialog). If you look into src/screen.c, there is a structure "formats"
that gives you all supported elements. Neither of them uses external
commands.

External panelize (src/panelize.c) calls a user-specified command and
opens a pipe to read its output.
But I don't think this code will ever be applied to the mc sources. This
option would make mc too slow, and most people won't use it. When a
feature is rarely used, the code can be easily broken by further changes
without anybody noticing it for a long time. There is not enough manpower
to maintain bloated code.
