That can be accomplished with the "meatware" STONITH device. Requires a
command to be run to tell the wannabe primary that the secondary is
really dead (and, of course, you had better be sure that the secondary
is really dead before the command is run to avoid split brain).

I don't know any way to do that exactly, but you might be able to use
order constraints to require some sort of ping-based resource to be
successfully started before the other resources can start.
