I am not convinced that it would. The quick team will get to learn three times as much and adapt to the actual customer need. The cost of change in a system built with stability as a quality attribute will be higher. (As you can see from a system like the old mainframes!)

The advantage that the original cobol people had is that they had functional manual processes to model.

Today, the payroll supervisor has no idea how many processes work.

Mainframes are expensive because they're niche and basically a duopoly. The companies supplying them know their days are numbered and charge high prices before the market goes dry.

In my experience, the quick teams only learn the surface content. A lack of depth tends to result in more errors down the road and poor architecture. But I guess it doesn't matter since half your team will jump to the next project company in 2-3 years anyways and take that knowledge with them.
