You can already store a (much) larger kernel.  The kernel is stored in the 
RedBoot partition, and that partition has a substantial amount of free 
space.  For instance on a TS-7250 you have just under 3MB; 256KB is taken by 
RedBoot, and 1 block (128KB or less) is taken by fisdir+fconfig.   The TS11 
kernel takes 768k (rounded up to the nearest block) so this leaves nearly 
1920k; your kernel size could triple and still fit with room left to spare 
in case of bad blocks.

I'm not sure you would want to re-order partitions, as there might be issues 
with how MTD or even TS-BOOTROM would find RedBoot.
