Ok, so
that pair in Oregon may be a little scary around the edges, but if I had to do small stand mounts, I'm looking for Reference de capos.
You mentioned DIY Mr. Fud (and I know you have mad woodworking skills) which to me is even scarier because the good bits cost and how do you get to hear them first...but this
Seas A26 kit intrigues me. A little bigger paper cone woofer (and the necessarily wider baffle) & textile dome tweeter that are complimentary enough to get away with a nice simple 1st order crossover - kind of down the same path as the de capo. Even reasonably smooth impedance and sensitivity that might just get along very well with el84s.
Crap shoot without hearing them but there is some buzz & posted opinion (FWIW!!) out there on them, even talk of improving imaging (offset tweeters) & bass (larger boxes) if you want to get creative with cabinets. Some even talk about displacing smaller Harbeths with these and their is mention of 'Orangutans'. Yeah, sure, but hey, they are intriguing.
