Most of the time there just wouldn't be enough interested people for the board to stay alive for more than a week, and heyuri can be pretty hard to get into: you either love it or hate it.
Maybe a general "hobbies/interests" board would be a good solution? It would be slower than /b/ and your thread wouldn't die from natural causes in 1 week, something which could be useful in a few cases (especially since we don't have a live archive)
The consequences of this? The hobbies board would likely be a dozen "general threads" about people's interests, activity would be split between 2 boards, and off-topic would become even more off-topic (・∀・)
So this idea does have its pros and cons.
