No, but if these companies migrated to 3DS as some people want them to do, these games would probably sell the same or less than what they currently sell. The few instances of niche RPGs more geared towards PSP/Vita audience in both 3DS and Vita usually sold a lot more on Vita, so publishing the game in a system with 6 or 7 times the install base (at the time) didn't mean more sales.
To migrate to another platform, these companies would have some cost added, some logistics to adapt themselves, etc. That means adding risks for no reward.
There is no point in ever migrating to 3DS, unless they are changing their target demographics and making different games. Given that the PS Vita will outlive 3DS, since the former will likely have no successor, the best bet for NIS, Falcom, Gust, Compile Heart, etc, is to remain on Vita while it is still relevant, then assess the market to see where is the best place to migrate, be it the next Nintendo handheld, consoles, PC, mobile, new gaming devices that may appear meanwhile, etc.
