This reminds me of Jan Tschichold's unicase experiment
The only thing i would say is that the caps need to be lighter

Thanks for the comment. It certainly is a unicase experiment ; or rather a take on the banning of upper-case by some bauhaus theoricians.

Brasilia is the name of the font, I probably should have explained.

My mind is slow tonight. I should have said that I have to play around a bit more with the weight of the upper case. It has to be markedly darker, narrower and with a larger x-height with a smaller stem height. Still, I can probably lighten it up a bit...

• Brasilia is the name of the font, I probably should have explained.

…And that name is taken. A typeface called Brasilia was designed by Albert Hollenstein and Albert Boton in 1960. It is now available from a number of distributors—as part of the Monotype’s Creative Alliance font library—under the name of Brazilia. Apparently, the design of Brasilia/Brazilia was inspired by the architecture of the new capital city of Brazil, which was the hottest thing going, in 1960.

This shows more promise than I would have expected (since I'm not a fan of this style). But what I would do is make it more display, and more interesting, by: dumping the current lc; making the current UC the lc; and making caps -maybe that only reach the x-height- with mostly traditional structures. I think then the results might even be nicely saleable.
