I guess that's the way to go since the biggest problem for small manufacturers is in the 0.5mm BGA. This is not an easy chip to start building your own product with...having a doughterbord with all peripherals accessible could help a lot. It's a trend in embedded PC's too where formfactors like ETX en DIMM connector-based dougther boards are more frequently used these days. Even in commercial products. Minor problem in this case: there's no standard like in ETX. As for the IO/motherboard, besides all available peripherals on the LPC2888 it should have an ethernetcontroller(pref. 10/100). A starterkit/evalboard can not be taken seriously without it (but that's my opinion...) Besides this, an evaluation board is as good as the software that comes with it. If you want something unique, include some unique software! There's a lot of good open source stuff available, so the trick should be in composing a good packedge and adding some useful drivers and documentation.
