The only potential catch is that this is a lot MORE targets for espionage. You only need to find one person with some life circumstances (new kid, long commute, conflict of interests, etc) and spearfish/blackmail/torture/teach scala accordingly.
Granted, your proposal does address a lot of things, but this is something that would need to be addressed. Thoughts?
It does give more targets to potentially get an insider into office, but the benefit gained by corrupting you local congressman by lets say forcing him to learn clojure is now limited as he is only responsible for .0003125 of the congressional power. If you managed to convert your congressman to be a lisp hipster you would control .001 of the congress ( and potentially more due to the current power arrangement )
There are many, many more people with access to sensitive/classified information in the executive branch. Increasing the size of congress by an order of magnitude will not meaningfully impact that number.
