It's a bit late now, but using AES might have been a better option.

The man page suggests that -m can be used to specify modules that should be
included. I haven't tried that myself though.

I think the idea there was to pick something reasonable and not provide a
way for people to shoot themselves in the foot. If you really care, you
can set up the luks devices before doing the install and you should be able
to use them by supplying the key for them. If that doesn't work, it's probably
a bug that should be reported.

You could try filing an RFE against anaconda that it determine the modules
needed for any luks devices used during the install and make sure there are
included in the initramfs image that gets built.
