It may not work.  The mkinitrd process would need /etc/modprobe.conf to be 
edited to match the new hardware/module configuration prior to rerunning 
mkinitrd (whether by hand or in the kernel %post scriptlet doesn't matter), 
or command line parameters have to be supplied to mkinitrd to match the 
modules you need to load.  See my previous message in a different thread, 
last couple of paragraphs, for a specific example.

When anaconda prepares your system for its first boot, it does a lot more than 
just run mkinitrd.  The grub configuration is just as critical as the initrd 
is.  Flagging the /boot partition as 'active' is too.

Like in tuning antennas, you need to engage in some trial and error to make 
sure it really does work  the way you think it should.
