Last night I salvaged the headset of a frame with about that level of kink in the downtube, The fork looks like a bates canti-flex... but i started thinking... I have that crap 1" threadless alloy fork. I could slap that on and ride this as a beater fixie until a nice frame falls into my lap for the my phil wood track hubbed wheelset.... so yeah if it were basically free I might ride it.
