As much as that would be awesome, Towers doesn't need any more thrill rides in reality. Although all 3 areas are in need of an additional attraction, the priority needs to be to get some more 0.9 ~ 1.1 mtr height restriction family rides. I don't think flats would fit the bill here. It already has Heave Ho, Marauders, Blade and Enterprise for this, although I agree a couple of lower height restriction flats wouldn't hurt in reality.
It's whole family attractions the park is missing. They could start by sorting out Duel and the Rapids then in my opinion, a Flume is needed and at least 1 more family dark ride (hint hint, bin the Dungeons off and put a new dark ride in there). Reopen the cinema again, perhaps a new indoor soft play and suddenly you have a much more appealing park again. Perhaps a new family coaster would be in order for an SW but I couldn't see it pulling in the crowds.
