Based on theoretical considerations, I'm sure I do not keep enough seed to maintain good diversity.

I taste poisonous tubers, leaves, and fruits pretty commonly. No big deal for a plant breeder...
Of about 300 tomatoes that I grew last year, one had poisonous fruit.
When I grow potatoes, about 15% of them have tubers that are too poisonous to keep.
The cucumbers are always flirting with being too poisonous.
I'm careful with melons and squash to not stray too far away from domesticated strains in order to avoid introducing poisons.
The only time eating poisonous plants got me worried about my well being, was after I had eaten a lot of a type of nightshade berries. They were exquisitely tasty. But about 6 hours later, just the time that nightshade poisoning manifests, they hit me like a baseball bat to the gut. I got out of bed. Positively identified the species. Put a sample of them on the nightstand beside my bed. And wrote the name of the species with magic marker on my chest, with an apology... Just in case I died during the night. Then I went back to sleep.

Tomato - i doubt a perennial is possible,
I disagree. The genus contains a number of perennials, most probably 2N=12.
The problem is that many of them also contain lots of really interesting (for which read "lethal") alkaloids. What I would do is identify one of the low-toxicity perennials in the same genus and cross until you find one that isn't sterile or that you can propagate vegetatively (the tamarillo (S. betaceum), naranjilla (S. quitoense) or the pseudolulo (lulo de perro) (S. pseudolulo) would be candidates: tamarillos will hybridise within the genus to sterile offspring, but you might be able to propagate the hybrid vegetatively). If you find one that's not sterile you could try backcrossing it with the tomato, I suppose.
It wouldn't be a tomato, but something new - but luck and forethought might result in something analogous.
All the latter plants are wide open for breeding work in their own right, as are others in the genus.
I do recommend being very careful when testing new hybrids in this genus, however.
