This is just an off-the-cuff thought, but I would avoid a welded steel floor, and look for a trailer with flooring which can be easily removed, since it won't be the floor you later want with the teardrop body.
Another factor would be axle position: it should be adjustable, or in a suitable location for the teardrop configuration (tears are normally tail-heavy, so the axle is relatively far back along the body).
How about sides? Utility trailers sometimes have side rails, which I think are a great idea on a utility trailer, but will be in the way (if they are welded on) of at least the door of the teardrop.
Whether the wheels are entirely outside of a rectangular deck, or entirely below a flat deck, or set into fenderwells, should match the configuration of the teardrop.
I think that if a lot of rework of the structure will be required to adapt the trailer, then there's no point in the conversion, so it should match the teardrop design or the plan should be to start fresh on the chassis and just sell or keep the utility trailer.
