The answer is no. On the contrary, standardized equipment affords many benefits. You can save time dealing with spare parts, know-how, expertise and so on. That makes it much easier to collaborate. The problems start when the equipment is highly diversified.
I don't know of any weapons system that has been systematically undone by a strategy. In fact, when that does happen, the situation is corrected quite quickly.
Lastly, in view of the cost to develop and maintain these aircraft, you absolutely have to have economies of scale. For the industry, that is the only way to succeed. As Canada does not have a national weapons or defence industry that would generate immediate dividends if the government bought a Canadian product, for example, there is ultimately little interest in breaking away from that group. I see far more advantages than disadvantages in that.
