16bit modes don't *have* a palette, to begin with, so the whole
problem doesn't really exist. Allegro (and maybe other libraries) may
obscure that fact by offering a 'seemingly paletted' mode for 16bit
images, but a the heart of it, there is none.

As long as you stick with originally 8bit paletted input images (your
usual GIF, e.g.), there's one drawback to keep in mind, though: while
you can only use 256 different colors in one such images, those are
choosable from an 18bit (256K colors) color space, or even full 24 bit
ones. So a GIF is not displayable perfectly in a 16bit mode, to start
with. But mixing two GIFs on the same screen does not pose any
additional problem, either.
