I believe - if the experience of the last six decades can be trusted - that the business case for a stand-alone Gibson bass division is somewhat limited.
Probably even Henry J, the young investment banker who played bass and was there to reorganise a Gibson Company on the brink of insolvency in the mid-eighties, based his decision to buy the whole darn thing (together with some business partners) on something else than just profitability expectations, maybe he liked the idea of ressurrecting a name brand. And in truth: Not everything he has done in 30 years was horrible. Unfortunately - promising start, but too long at the rudder - he's slighty turned into a "Nashville-Mugabe".
Incidentally, what is the status of guitar and bass sales today? Do they continue to climb or are they on a descent from a peak hit, say, two decades ago? My hunch is the latter. I read an interview by Herr Wilfer of Warwick who mentioned that even his company almost capsized a few years back. And Warwick - whether you like the product or not - seems like a well-run company with quite some market penetration (given its less than huge size).
