Like the Longbow with its LRMs and the Awesome with its PPCs! Right?
There are two arguments against it, one from the gameplay point of view, one from the eyes of the developers:
1.) A Stalker is not an Awesome. Yes, it's true!

Some Awesomes are meant to be a PPC-boat, this is correct. But the weapons are placed on the body so that an Awesome would have to expose itself fully in order to fire them all together. It is shaped like a brick-wall and can easily be hit. It is a PPC-boat, but there are disadvantages that balance the build. The Stalker just has to stick it's upper heat out, peek, shoot, retreat. The current meta in a nutshell.
A Stalker is also not a Longbow. Only a Longbow is a Longbow.

2.) Hey there PGI, I heard you want to make money...
Okay, so you say there is no need to limit customization, everything's fine and a Stalker can be a Longbow. Cool. Just wait until you release the Longbow and nobody wants it because the Stalker does it better. And who needs the Awesome as a PPC platform?
Yes, I do believe that players buy mechs because they like how they look. But it is rather shortsigthed to rely on this alone. When the players realize that the Stalker is the better Longbow, they may have already payed you money, but they may stop playing. And you know what makes World of Tanks so successfull? It's huge player base. (And in contrast to the "hot news" that the player base continues to rise I see the same players in just a couple of games and then again, so I really don't believe it!)
If you want to sell mechs in the future and if you want to retain your playerbase, you need to shape mechs so that every build has something special and be it even small.
So there you have it. My 5 cents to the annoying "mech x does it" argument. Flame-on.
