If by current you mean it will work then yes.
I would use a bulkhead triclover fitting rather than trying to solder and bolt the copper to the lid.
Make the outlet as short as possible, this prevents smearing.
Obviously a stainless needle valve would be a winner here as well.
Have you thought about the double reducer style?
Supposed to be easier to make.
But do you really want 8-12hr spirit runs from a keg full of wash?
Or are you going to scale it up to 4"??
