I think we need an evangelical Bible society. There are of course many evangelicals in Bible societies and many Bible societies with an evangelical ethos. However, at present, UBS does not have a consistently explicit evangelical approach. Why should it? The Bible does not belong to evangelicals. UBS does lots of good work that does not need to be duplicated. However, there is a case for an evangelical Bible society that is able consistently to apply evangelical principles in commissioning Bible translations—evangelical principles about text, translation and canon. The Gideons is, of course, a great distribution network for Bibles. But it does not commission Bibles.
The advantage of an evangelical Bible society is that it also might be able to be a market force to counterbalance evangelical publishers. They each like to have their own translation since translations sell well. An evangelical Bible society would not be for profit and would be able to put pressure on publishers not to use Bibles as a source of profit.
The Trinitarian Bible Society was, originally, a mainstream evangelical Bible society, with a rather broad compass (e.g. Edward Irving). Its exclusive commitment to our beloved KJV has, however, meant that it can no longer serve the mainstream.
