It would be a hard task, especially given that he'd never finished the design. The credit for the Difference Engines (No.2 in particular) lies as much with Clements (and latterly Doron Swade's team at the Science Museum) as it does with Babbage; while Babbage's basic idea is sound, there were a lot of detailed engineering problems that needed to be resolved before it would work.

For this reason, we're more likely to see a mechanical computer fashioned after Babbage's Analytic Engine plans than we are to see a working Analytical Engine per se.

If such a machine were ever built, it would most likely be made from silicon rod logic at nanoscale.
