I don't see why it couldn't, though I do think if you were to do this you should give it a name change to show the distinction. It could be interesting if you made a dueling coaster (one with the rockets and one with the jet packs, so families can ride). Or what if you turned the TTA into a Jet Pack tour, including some rollercoaster elements...does that make sense? Idk. My fear is your park is becoming a little too thrill-centric. One of the great things about MK-coasters is that families can enjoy them together, with only the youngest riders not being able to ride...
And you know, my park does have many thrills, but most of the thrills are mild like MK. Here, why don't I give you a basic run down of the attractions in the park and you can get a better idea of the park overall:
