At the expense of reducing the strength of your authentication (and potentially the confidentiality of your passwords) to that of an ad-hoc stream cipher based on MD5 -- unless you encapsulate RADIUS in something else, which adds some complexity but would work.

If you migrate all the password information into a radius server, that can handle both linux and strongswan login.
