I say go ahead and transplant, too. Do you have help? If you have some strong guy or gal to do the heavy work, I think you should be able to transplant them with a minimum of shock.
I haven't used smart pots, but I would worry about them drying out faster than regular pots. You mentioned the humidity on another thread. Check your humidity in the late afternoon when it is really warm. Mine is 55% right now, but will drop to 20 or lower when it gets hot. I think the arid climate would dry out the smart pots faster and make it harder to keep them watered. I have several 15 or 20 gal pots that I plant tomatoes or potatoes in sometimes. They are plastic and have rope handles on each side. Something like that may be better. Also, most places now are having closeouts on summer stuff so if they have any large pots they are probably on sale as they don't want to store them over the off-season.
Pink Momma looks like a Christmas tree. You have every right to be proud of her.
Wish I was there to be one of the helpers. I'm sure transplant will go fine. You have a wonderful green thumb.
