Obviously you need to find a bearing with the same outside diameter as your current 8mm bearing

so if your current bearing is a 608zz it has an ID of 8mm and OD of 22 mm and a length of 7mm

A quick search of simply bearings produces a

W61900 2Z which is a 10mm ID, 22mmOD but only 6 mm long.

Also, most stub axles have 4 bearings in the kingpin, 2 at either end, and a separator that runs between the bearing sets.

You could run the narrower 10mm bearings, making sure they seated properly on the internal seat, but it would be best to make up the internal separator as well ( a piece of 10 mm ID tube) to support the inboard races.

Your other problem will be that you need to find extra yoke spacers, because your bearing stack will now be 2 mm shorter top and bottom (ie 2* 6mm long bearings wher you had 2 by 7mm bearings).

Not impossible, in fact quite easy....but if you don't have any mechanicing skills at the moment you might feel challenged!
