I don't mean to be a wet blanket, but I want people to have realistic
expectations as well.

I would not expect the -preempt, -rt, or -realtime kernels to be maintained
in the official archives (repositories).  These would need to be maintained
in a PPA, although it is probable that this could be maintained in an
official Ubuntu Studio PPA.  It is my understanding that these kernels
cannot be included in the Ubuntu Studio ISO if they are not in the archives.

I would expect the -lowlatency and -generic kernels to be in the archives
and therefore can be included on the ISO.

Therefore, my suggestions would be to focus on the -lowlatency (which will
need to be community maintained and in the repos) and the -rt kernel (which
many users desire for performance but maintained in a PPA).
