Nooooooooo! Please, not free as the British Museum for at least three reasons;
1. The British museum is full of pieces stolen of other civilizations and for people of these regions to see the pieces they have to travel to London
2. There is some policy regarding how the museum collection is lended to other places, in order to people who cannot travel to london to see the pieces. And this policy is not public, is not open in any mean you can attach to it.
3. Last, but not least, to enter the UK you must be accepted by immigration staff.

I got your point, but your example is quite bad for people from outside UK.
