I'm right now investigating the possibility of doing something similar, but with a small alteration... I'm looking at using the Dynalite calipers rather than the Midilites. I've found a model that is pretty much the same specs as the ones used on the conversions here with a couple of differences, mainly the cost which is USD 350 aprox with shipping to Argentina and Bp10 pads included! Although they don't come with dust boots that won't be an issue over here.
Now here is the question:
Since the Dynalite calipers are not radial mount, but lug mount I'll be having the brackets specially made to fit these to the 306 hub but are there any difficulties you see before hand with this bolt arrangement? Anything that might make it impossible to fit these lug mounted calipers? Would the bracket design be too complicated making it too heavy/unstable/dangerous?
Here are the caliper details and schematic:

From what I can see the outer part of the caliper is much slimmer than the midilites which might make it possible to mount these without spacers under cyclones. I'm I right here?
Here are the details for the Midilites:
