I love the thread idea, and all of your candidates would be fine additions.
The concerns I'd have with Victor Cruz:
1.--he and the NYG are currently having problems regarding his new contract. It's hard to try and assess what they've offered him, but I'm going to take a stab at around 10 million dollars. The WR market continually goes up every year much like the QB market, at least for the elite receivers. Last year we saw guys like VJax setting the standard at about 11 million aav, this year that went up to 12 million aav with Wallace/Harvin. Next year Cruz has the potential to at least bring in what Wallace/Harvin did at 12 million aav.
That means we'd have to set a price that would outweigh what the NYG are willing to match, while at the same time being careful not to underbid at set the terms of their contract for them. In other words, the NYG may very well end up losing Cruz next year if they don't want to pay him 12 million dollars a year, and all accts point to them losing him. If we bid in at 10-11 million and they match it, we'll have just given them a discount and allowed them to retain Cruz for another 5 yrs.
2.--I have a hard time seeing Belichick part with a 1st rounder since they are known for such awesome value. We have a great track record in acquiring 1st rd picks, and have the potential to lock up a very, very cheap and productive player for the next 5 yrs. Obviously the good teams are built through the draft, and giving up a 1st is risky in itself. Cruz would obviously be worth it--but at a very high compensation. That tends to almost offset the move in a way.
3.--I also have a hard time seeing Belichick give someone 11+ million dollars a year at this position. Considering that we'd have to do that AND give up a 1st round pick, we may seriously as well look into bringing in anyone of the top talents in the NFL including Revis, Fitzgerald, etc. They may take an additional pick next year in the draft, but you may get someone to agree to a 3rd round pick or so in 2014. It would likely be worth exploring that option IF you're going to give up a first and pay them 11+ million.
To sum it up, I love the idea of exploring other trade options for the WR position. Most of them aren't going to be cheap, so we need to think about the value too. Although Sanders isn't our ideal choice in this situation, putting him in the mix with Brady for a few seasons by giving up a 3rd round pick and approx. 6 million a year may not be such a bad idea when you consider everything else.
I would also like to still choose a high draft pick this year since most of them take a year or so to get acclimated to the system. This would assure us a mix of youth, speed, depth, and experience to our WR corps--all while providing good financial value. It would address the need for a revamped WR corps while allowing us to stretch the field more and get younger at the same time.
If someone else comes up for a potential trade like any one of your options, then I would hope that Belichick gives them all long thoughts.
