Not really...alpine females can be rather nasty. They are agressive eaters that don´t let go fast if they mistakenly bite someone´s leg. Other than aggression, i´d fear the orientalis may be outcompeted.
However, even if they cohabitated peacefully, there are other reasons why keeping them together is just not a good idea. The thing to remember is that they gain nothing from being kept together, nothing whatsoever, but they do become susceptible to certain risks. The only one that can possibly benefit is you, and personally i consider the benefit to be extremely trivial and certainly not worth it.
