well it would be a good base for a conversion.
i would take off the trunk to start, then put the tusks somewhere safe. then add a HUGE mouth, in proportion to the rest of it. add the tusks back in there
with the howdah, no cloth sides. plasticard some plate onto it, then a kannon or three.
i dunno, a very extensive conversion.
it would be a good base, but for all the effort i would just get a squiggoth.
