I wouldn't worry too much about this kind of optimizations - the page compilation happens only once and it's quite easy to pre-compile the pages with jspc. The place where optimizations do matter the most is the runtime - I would be happy with a generator/compiler that is slower but generates faster code. Even if it is possible to use BCEL to generate bytecodes directly, I think this would be a huge waste of time if done before the runtime is optimized. A clean generator that makes it easier to improve the generated code is better than the fastest generator.
