I did some wacky grafting a few years back when I worked in a greenhouse. I haven't messed with the idea since, though. My biggest accomplishment was grafting four different species of cacti to a candelabra euphorbia (still a succulent, but evolved on a completely different continent). As for the lychee tomato base, I'd try radiator charlies mortgage lifter. It's the thickest stemmed tomato variety I've tried. Really tasty, too, and prolific harvests due to the size. It is a mid-to later ripener, though, so you would have that challenge.
As for what seeds you'll get from grafting (I read this thread back towards the beginning), the genetic material is in the apical meristem (bud shoot) so no matter what you are grafting on the seeds genetics will come from whatever you are grafting on to the base, regardless of what you're actually grafting to.
