Hard chromed barrel tubes/monoblocking may be the way to go. Question - what barrel lengths and choke combinations are being considered. It would be difficult to grind out an existing tight chromed choke to open up; example, open a full choke to Skeet 1.

Possibly the initial offering could be 28 inch barrels with I.C. and Mod only - keep it simple! Another thought - would the group consider Briley chokes similar to the 28 inch RBL barrels?

If the barrel tubes are TIG welded to the monoblock, the seam would virtually disappear.
