Yes, it can be done rather easily. Rather than modify existing magazines for your 1911 type pistol, purchase a few Wilson-Rogers magazines, they already have a vertical slot machined into the sides of the magazine, where the remaining rounds can be seen.. Stocks could be a bit more difficult to find, you might try Carbon Creations to see if they have a clear set of stocks, Worst case scenario, is that you get a set of wood stocks for the 1911, and cut out witness holes then cut a piece of lucite to fit and glue it in place.
