Cost? You mean the MX priority (as seen in host -t MX)?

While the question as I understand it is not a SA question, and doesn't
match the Subject either...

This oh-so-simple scheme won't work. Spammers give a rats ass about MX
priorities. That is, unless they actively target higher numbered MXs, in
the hope they are less protected.

(The latter, coincidentally, being exactly what you just proposed, no?
Highest numbered MX on-site, while lower will do the filtering.)
