Then I wouldn't do it. Jrue has missed a lot of games and comes in with a pretty high salary - not John Wall high, but still 26M for 3 more years is risky considering his injury history. And I doubt he'd be available at all, even if they were rebuilding, if it weren't for concern over that stress fracture that bothered him for years.
IMO a big part of Warren's value is that he outplays his salary. I think that has to be factored in when looking at possible trade scenarios. No doubt Jrue impacts the game much more than TJ does but age and money are on Warren's side. I think something like TJ plus the Milwaukee pick makes sense although obviously there would need to be fillers to make it work. If you're right and they need significantly more value than that I think we'd be better off passing.
Last year, someone (Eric, I think) suggested Holiday. I dismissed the idea due to his salary and I remembered some drama around his injuries. Earlier this year, after watching him play, I actually did some digging.
Let's start with these "injury concerns." I may be wrong, but I don't believe he's missed any time last year or this year, outside of one or two random games. The year before he missed the beginning of the season, but that was due to personal reasons (I believe he was taking care of his wife, if I remember correctly. This injury concern is nonsense. Sixers didn't disclose an injury, he had a surgery and some brief complications and that was it.
As for his salary, sure it's a lot, but it's not really that outrageous considering he is a good scorer, a capable play maker, and the best defensive guard in the NBA. Suns are OK financially for the next three years.
Also, he is 28, so I am not sure what his age has to do with anything. It's not like he is 35. Frankly, the Suns could use someone in their rotation who is not in the 19-22 age range. I am sure that an average team would prefer a 25 year old, but I think that's a very small factor.
My guess is that the only way Pelicans trade him is if they decide to blow it up since AD is leaving for LA. Even then, I am sure they would want a good player in return, along with a nice draft pick, a youngster or two, and some expiring contracts. I am guessing they would want Warren, one of the PGs, Suns's pick, Bucks' pick, and the expiring Daniels and Bender. I would do it. Holiday is locked in for a couple of years and he is literally the perfect fit with Booker. Decent fit with Ayton since he has experience playing with AD.
Oddly enough, if we take Holiday trade out of the picture, Warren would be the perfect fit on that team. There is enough defense to hide Warren, and he would give them additional scoring and shooting, which they so desperately need. Unfortunately, they have nobody else the Suns would want (that are not expiring contracts that could sign elsewhere.)
