Hi Xeramtheum,
I considered breeding Morning Glories, but the warm colors seemed to be mostly missing. Theoretically there is a yellow species, but it doesn't seem to have been exploited to widen the morning glory color spectrum to something comparable to zinnias.
I stumbled across Hidden Valley Hibiscus when searching for the Bug Blaster

hose-end water sprayer. I haven't bought one yet, but I still may. Hidden Valley Hibiscus has some amazing hybrids. If I weren't so busy with my zinnias, I might consider Tropical Hibiscus as a hobby.
I agree with your characterizations of F1, F2, F3, and F4. Now all I expect of the F1 plants is confirmation that I got the cross. I look forward to the recombinations of genes that occur in the F2 generations and beyond, which is where I make my main grow-outs.
