Okay, spent an hour digging through the FL statutes. LSV and golf carts are clearly defined. One ain't the other. Nothing is mentioned about conversions.
However, the Florida Motor Vehicle Mobile Home and Recreational Vehicle Dealer's Handbook DOES talk about conversions.

F. LOW SPEED VEHICLES
<SNIPPED SECTION OMITTED>
"Used and new golf carts that are converted as golf cars with a maximum speed greater than 20 mph, but not greater than 25 mph will be titled as assembled from parts (ASPT).
Dealers who sell used golf cars or golf carts converted into LSV’s must be licensed as independent dealers.
A golf cart that is converted to a low speed vehicle conforms to title 49 CFR part 571.500 and section 316-2126, Florida Statutes, and must have the following:
Headlamps; Stop lamps; Tail lamps; Front and rear turn signal lamps; Windshield with an ASI or AS5 composition; Type 1 or type 2 seat belt assembly conforming to Section 571.209 of this part, Federal Motor Vehicle Safety Standard No. 209, seat belt assemblies at each designated seating position; An exterior mirror on the driver’s side of the vehicle and either an exterior mirror mounted on the passenger’s side of the vehicle or an interior mirror; Parking brakes; Reflex reflectors: one red on each side as far to the rear as practicable, and one red on the rear; Windshield cleaning device pursuant to, section 316.2952 (3) (4), Florida Statutes; Horn pursuant to section 316.271 (1), Florida Statutes; Slow Moving Vehicle Emblem (SMV) pursuant to section 316.225 (7) (a) (b) Florida Statutes; and Illuminated rear license plate bracket."
So it can be done legally statewide, provided you follow the extensive requirements. Shame this isn't mentioned in the Statutes...
