It definitely wouldn't be welcome by the kernel team.:-).
I think what you're looking for is an application server that can be
started early (perhaps by a Linux startup script) and handle requests
for classes to load and run. There are a lot of challenges to doing this
well, and nearly impossible when dealing with GUI apps... but it's
possible if you make enough simplifying assumptions :-).
