What you try is not implement. You simply have to understand that mkgmap cannot read data in gmapsupp format. All the mentioned files are in gmapsupp format. So, either use a different tool or maybe split the gmapsupp files first, e.g. with gmaptool.

so I tried combining [opentopomap] Hungary and Slovenia but then I get again a small 2.5KB file
Same here. My test were on simple maps without routing and DEM only; maybe its that. Sorry. //Felix
