Using LSB-si as build-up platform

I want to use LSB-si to implement my own LSB linux system. The linux system
in my mind is a light-weight linux combined with Java Servlets and JSP using
Apache Tomcat. Is it reasonable to use LSB-si to start building up such a
system. If not, is it an idea to build a LSB-minimal standard implementation
to do this?
