I came up with this design a few years ago and I have been using it ever since. It's time to share with whoever wants it. I think it might be a contender for the smallest possible kovarex design. Feed both kinds of uranium in on the left and your extra 235 comes out on the right. A benefit of this design is it's very easy to elongate the transport belts and insert some beacons in there. Also, because input comes in on the left and output on the right, you can chain them together, you just have to add more 238 to each one.

Here's a low tech variant running in my current game:

Here's a version of the blueprint stretched out with beacons. I haven't figured out how to get the last beacon in there, but I'm not really motivated to try.

I stretched the beacon version a little too far. Easy fix. (I've never used this beaconed blueprint, I built it just now to prove if it really was that easy to modify it for beacons and it was.)

Might still not be the smallest setup using belts:

Take the filter off the '235 loader, replace the '238 loader with an underground exit, the back '238 unloader fills, that saves the side lane.

I did not want to miss some 235 without the input filter, but practicality is not really the goal here anyway.

I have this one:

I think thats the smallest possible, got it from the forum I think, you dont need the beacons and can tear the units apart, this is just a small module that is balanced, ie it makes enough uranium to fuel the kovarex.

Really, though, I think you can start with the one on the left here and extend to the row as desired:
