I doubt it would be worthwhile making a bomb with an element heavier than
plutonium, pre-detonation would be a real problem so you couldn't make a
very powerful bomb, and it would be as expensive as hell.

Actually, atom for atom tritium is 3 or 4 times as expensive as U-235
or Pu -239, pound for pound figure 2 to 3 hundred times as expensive.
And the half life of tritium is about only 11 years so you must keep making it.
Most of the tritium in a H bomb is made in a fraction of a second from a
blanket of lithium when the fission trigger goes off.
