Modifying the random algorithm won't help you because Rockbox decides
which tracks will be played and their order when you select the
playlist, not at the end of each track. It would require some fairly
significant changes to the code to support the functionality you want.

Each playlist entry requires 4 bytes of buffer space so switching from
20000 to 50000 will reduce your buffer by ~ 120K. Unless you're using
one of the Archos devices, this amount of buffer space is negligible and
is definitely the best/easiest option for now.
