If the fuselage is still largely intact and on a slope, the profile presented might be more the cross-section of an 18 foot hollow tube, rather than a nice horizontal presentation of 150 feet or so of metal.
Can't say how many segments the fuselage is in now. The sea surface and bottom impacts can each make a contribution. I venture the best candidates for large components would be the wings and centre section. Then there's how they will array themselves on a slope or collect in a hollow possibly with avalanched slope debris on top
A nice long cylindrical section could roll down a slope or could hang up on a bench or projection or end up on the bottom of a slope.
It would take a lot of cheap airframes to work out the many ways the pieces might come to rest on a contoured bottom.
There have been sonar searches for historic wrecks on reasonably flat bottoms that have taken years.
