Calipers have a disc thickness range that they will work within, normally around 4mm. So the M5 caliper will work with 34mm steel discs no problem.
The height of the discs is down to the fabricator, so you can of course have a narrower friction area and wider bell if necessary - this is completely adjustable. For a particular pad width, there are normally a range of pad heights available to work with a particular caliper.
