I agree! If you really wanted to, and you feel like Phantom would eventually like speed events, then you could work on his training and have a horse just as fact as TC. (TC is weird to type, I ride a horse named CT lol)
I'm sure Phantom will appreciate you if you let him do something he likes. I ride tons of horses, but I still ride my older mare on trails when I have extra time. She enjoys being able to relax under saddle and in the pasture, and I'm sure she's not "jealous" with the other horses who have to work hard! ;)
But I mean, there's no reason you can't ride both...
