If the intent is to have a play with tunnel diodes, then why not? Have some fun!

If the intent is to create a GDO, then don't bother. The heathkit ones proved that though it could be done, the end result's performance was seriously disappointing, and not good enough for most day to day uses. On the other hand, there are much superior dippers using valves, bipolars, FETs and even the triode part of a magic eye has been pressed into use. Take your pick.
