It (likely) won't happen, for the reasons mentioned above. Additionally, It puts the screws to retailers. People tend to forget about them, and their part in the hobby community. (For the record, I am not one, but a good friend is.) Word of mouth, forums, and internet sellers are great, but what really makes a game move is seeing it being played, and seeing the models up close, and talking to people who are playing. All of this generates excitement and buzz, and gets people interested. If FFG were to make stats for all of Tamiya's 1/48 kits, and they become a significant part of the game meta, you're not just taking that money away from FFG, but from the retailers, who have to either accept that loss, or additionally carry another product line in their stores to support the game. Maybe FFG could force something like this on retailers if they were a GW-sized force in the market, but they are not. Angering the retailers you rely on to carry your product is not good for business. As it is, FFG already gets the blame for the Rackham debacle (the ceo of FFG addressed this in a BGG thread), and retailers stuck with a ton of Rackham product they invested in are already skeptical of an FFG minis game which involves former employees of Rackham. It is possible that, if Dust is particularly successful, and has a large enough player base, such a thing could happen. But not any time soon, and likely not ever.
Additionally, if fans are already creating these resources, I would expect that most casual gamers would be more than willing to allow you to use them in pick up games, especially if go about it as though you're playtesting the points values, and agree to also play a game or two with strictly Dust models and stats. If your desire is simply a modelling issue, there's nothing stopping you from proxying Shermans and Tigers for Dust tanks in your force. Most people would be okay with that, especially if you have the skills to make them look really good.
Further, "play another game" is no more a BS argument than stamping your feet and huffing and puffing that evil FFG won't listen to you. Hobby market game companies make the games they want to make. Since they are typically staffed by gamers, this generally translates to making the games they want to play, which usually (but not always) translates to games other people will want to play. FFG and Dust Studios wanted to make a game about robots and elite units. You want a game about conventional forces with some robots and a few elite units. In this case, FFG did not make the game you wanted. Stating your case once is good customer feedback. Continuing to whine about it on the forums they host is poor form. Admittedly, if FFG were to step in and say definitively why they won't do what you want, you might have little reason to continue complaining. But either way, they didn't make what you wanted. You have the option to play anyway, or go elsewhere to satisfy your gaming appetite. Crying about it here helps no one. If it's really that large an issue for you, try contacting customer support with your request, and leave it at that. I've no idea if you will get an answer, but at least it's a somewhat constructive use of your time.
