Hi Stevie,
I really like the initiative. There are a couple of things that came to my mind that might deserve some consideration.
1. You intend to send this to those 73 UK MEPs whose legislative turn will be over in about 2 months. There will be some considerable turnover. One option could be to adjust the recipient list to all candiates for an MEP seat or those with realistic chances of getting elected. After all, those candidates might be in a good mood to listen to suggestions right now.
2. The term "Public domain of publicly-funded works" might be perceived in two possible ways: Open Access to publicly funded works and Public Domain of Government works. Given the framework agreements such as Berne Convention and others, it will be unlikely to deny copyright protection just because funding came from a public source.
3. I really like the idea of illustrations. The picture of Big Ben and a crossed out European flagpole installation however might be interpreted slightly different than intended. Spending time and effort (and possibly even money) to get a layout that is appealing to the eye is definitely worth it.
4. Size. Three pages might exceed the attention span of your target audience.
