Canadian and Australian yards could build Tribals with the standardized 4.7-inch fit, widening both production and ammunition commonality across Commonwealth navies. Indian yards might also complete hull work. The limiting factor would often be manufacturing and delivering the machinery plant required for destroyer speed, rather than the yard's ability to assemble the ship itself. The scenario expands industrial options while retaining a major shipbuilding bottleneck.

Commonwealth yards do not eliminate machinery bottlenecks
Canadian and Australian production could spread a dual-purpose Tribal programme, but propulsion machinery rather than hull-building capacity remains a major constraint.
