So that could work...

Sorry to be a party pooper, but I have never had my $12 nozzles leak from internal junctions - ever. There is a brass nozzle attached to what appears to be a steel cylinder which heats up and pre-melts the filament before it's pushed into the hot end - there is nowhere for it to leak. I've been through close to 50kg of filament.

I am still having trouble understanding the short 'melt-zone'

can you explain that in a bit more detail please?
