A salvage destroyer is completely unnecessary. For starters, the existing meta where 1. exploration frigs have salvage bonuses 2. non-bonused salvage destroyers are fitted well for salvaging 3. the Noctis is great and not terribly expensive 4. MTUs can be used by any ship in addition to or instead of their own tractors is just fine. We don’t need to squeeze in a fifth meta - it is not needed or beneficial.
I cannot emphasize enough that the Noctis is not expensive at all whatsoever. It costs less than half of a T1 battleship and less than a T2 mining barge. Do we really need a junior/inferior version of a ship that is already cheap? A well fitted Noctis already has high agility and great also, so it’s not as if it is too sluggish or flimsy to be impractical to use.
Some of your proposed stats are also absurdly high and even have features the Noctis doesn’t have (why???), though really the concept itself as a whole has to go.
Older vets want to see less, not more. For starters, the MTU has to go. Here is a classic older vet sentiment:
Introducing a salvage-bonused dessy makes a bad situation worse in that the Noctis is already a grossly neglected and underutilized ship (due to the MTU mistake) even though it is extremely affordable to use. We’re not going to address this imbalance by introducing an unneeded and unwanted ship. (Speaking of unneeded and unwanted ships: look at the mistake CCP made and is still making by introducing Trig and EDENCOM ships)
