This sounds very interesting.... I have a couple of old shotguns that would benefit from this. Is there anything I need to tell the plater, other than the desired thickness?
If the plating Company you are dealing with are on the ball then no. Just to take great care in the masking.
It pays to make a dummy screw to replace the one that holds the ejectors in. This is for 2 reasons. First it stops the internal thread from being plated and built up. Second you leave it very long and they clamp the electrode there so no other part of the barrels need to be un masked. After use throw it away or keep it for the next one.
This is a common practice done in industry all the time to restore turbine shafts, bearing shafts etc. Imagine what the cost would be on say a hydro electric turbine , if you had to replace the entire shaft for wear, rather than plate it and regrind to dimension. A £ 50,000.00 shaft can be repaired for £ 1000.00 of plating and grinding. It is done on Aero engines and helicopter jet turbine shafts.
Bear in mind that when plating lugs then you always get some extra material deposited on the external edges, this is due to the way that electrical current flows. No problem, but the "feathers" look terrible when you first get it back, but they are excess anyway and you dress them off.
