Yeah exactly (except I’ve only got one stay mount on the mudguard, in the same position as the lower ones on yours). Other option would be to use the lower mount on the fork (by the dropout) and use a good sized spacer to push the stay out so it clears the calliper that way.
Not mine. On my last bike I just opted for a big spacer and long bolt to push stay outboard around the caliper. Have also seen done like the below. On single stay guards like Berthoud or VO sometimes its possible to mount so far round and down it simply passes under the caliper.
Like this?
