I'm putting a hard top on mine. Just to clarify your question:
hard top= fiberglass structure over helm to provide shade
half tower=same as hardtop but made of cloth
marlin tower=a second helm station directly on top of hard top or half tower
tuna tower= a second helm station with its own floor well above the hard top or half tower.
Are you considering a Marlin Tower? They put Marlin towers on the 24 Albe, so why not...
