With respect to most trades, whether one is fair or not is usually subjective - although being unfair or fair might be obvious to most GMs. However, to get a 4th rd draft choice (not to mention two additional 7th rd draft choices) for a 5th rd draft choice in the same draft is objectively unfair no matter the motivation. So no, I won't support allowing the same trade again.
If Tampa Bay wants, it may now offer to me the unwanted draft choices to me for equivalent future round draft choices. If after the trade is consummated any other GM wants any or all of the draft choices Tampa Bay traded to me, I will trade them for equivalent future draft choices right up to the moment I have to make a selection (assuming a trade offer allows me reasonable time to respond - I do have a life outside of MFN). I take all the risk of having to keep the draft choices (which I don't presently want); Tampa Bay unloads its unwanted draft choices; and other GMs can wait to decide whether they want have another draft opportunity.
