Yes you can get volvo calipers to fit the mini hub.
My setup used the 4pot volvo calipers with starrion vented disks and drum hub 1/4" spacer and the piping is a bitch.
Problem is you need 13" wheels that allow lateral clearance for the caliper for which I found only one brand and the setup weight of the whole lot is an absolute ton. Also the whole setup is held by 3 pissy bolts onto the drum knuckle (like most hybrid brake setups)

For 10" I run a mitsu caliper and a 8.3" dia vented disk
For 12" I get the feeling that Camira setup would be more then adequate (I have a set sitting in the garage ready for "Besser")

Besser - can you post more info about your 10" brake conversion?

to increase the strength of your braking system, so that it is not relying on those pissy bolts, make up a little plate that sits on top and bolts to the steering arm,, and weld it to the backing plate. make sure the bolts are tight before you do so. Problem is to remove your steering arms you may need to undo your backing plate if it is too tight.

The standard 3 bolt fixing is pretty strong, the hub is tapped 5/16" UNF. The bolts just look weaker than they are due to the small hex heads.
Even a drum brake system can lock the front wheels without shearing things off. But for the Hondas Civics & Citys I did, I fitted Grade 8 bolts...

Ben I dont think the mitsu conversion will fit with your mamba wheels. The Contessa tapers down closer to the centre line of the rim compared to the mamba and this is a critical dimension when clearance is down to 1.5mm

You know the R&D is half the fun and all the cost, so maybe you could find a setup for your Mambas

Sorry about the 8.3" it's mor like 210mm and yes it fits.

i have contessas

Havent seen them on anything I have found locally. I have taken to making my own backing plate even though the original was almost perfect.
