Dave,
Yes, I would suggest crossing the two of them both ways to obtain obtain at least 20 or more of each cross to see what you get in the first generation. This should give you a good idea of what you might expect if you continue on. You neve know what is lurking in the background of Gales Favourite.
Here is something like you might get something like these two seedlings - of mine. I would be very interested to see if you get any with the white extension (flare) from the nectary furrows. However, I have to say you may get something that is totally different and beautiful. You will only know if you give it a try.
