A Reuban has Corned beef, what you planing would be a Monte Cristo. Still very good but not a Reuban.

Depending where you live folks use different kinds of meats for Reuben, while the original/classic is with corned beef there are variations and really about personal taste.
For example here is Florida we have Grouper Reubens, some do Turkey Reubens, Veggie Reubens, there is a chain out of Wisconsin that sells Ham Reubens.
Heck I have leftover cb so I sliced the cb very thin, use a bit of thousand island sauce on the rye bread, add Swiss cheese and the sauerkraut and heat in a pan until everything is married!
Just my twist!
Brian but the Monte Cristo does sound good also.
