I don't think so. The hitbox closest to Ganon doesn't combo.
Up and away would be pretty good DI for ftilt too. So it would negate the mind game. Besides, according to your data, ftilt doesn't work until 110. So you have a 20 percent gap where regrab, dtilt and jab are your only options out of dthrow. So it's probably best to continue the chaingrab, uthrow, or jab until 110, unless you see them DI into the sweet spot of dtilt and you are absolutely sure they won't DI to avoid your uair/fair.
At 110, I think the optimal thing to do is to not even try dtilt, but to just down-b or ftilt in reaction to their DI. Down-b for in front, and ftilt for behind. The only problem is there are situations where it might not be enough to close off the stock. But the chaingrabs go really high, so it's important to recognize when down-b or ftilt won't finish it and just continue the chaingrab.
Example: You're near the edge of DL facing offstage and dthrow fox at 110. If they DI behind, your ftilt might not set up for the kill. They might be able to DI down and tech. Really good survival DI would also probably work. So in that situation, regrab would be best until he DIs in your favor.
