Cast & Crew say YES
Here are some quotes from Q&As, interviews and comments on social media.
Tim DeKay, Q&A session, December 15, 2014:
I don't know. That's a good question. I think in past I would've said "No, I don't see that being a possibility," but VERONICA MARS kind of broke the mold with that, so I'm not going to say that would be impossible. I would certainly entertain that possibility, but right now there aren't any plans to have a movie. Gosh, that would be fun.
Matt Bomer, Q&A session, December 15, 2014:
That's way above my pay grade. [laughing] If they came to us with the proposition, then I would definitely want to do it, just to get the chance to work with Tim and Willie and Marsha and Sharif and Tiffani again, but I have no idea.
Jeff Eastin, TVGuide, December 18, 2014:
[...] I think the idea that we come back for something like a TV movie would be appealing and after talking to everybody, especially Matt, I would say that everybody would probably be down for something like that if it came up.
Matt Bomer, People's Choice Awards, January 7, 2015:
I love everyone involved in that show so much that I would do anything with them anytime, and so I hope we get to reunite in some form or another at some point.

Treat Williams, Twitter, January 15, 2015:
I've done a lot of television. I think a white collar movie is a cool idea. Whether I'm in it or not.
Willie Garson, Digital Spy, April 26, 2016:
[Creator] Jeff Eastin did a great job, and I can't see why he couldn't come up with a two-hour something. I wish he would. But we haven't heard anything. We've all gone on to other jobs and we talk about, 'Man, this is not what we had over there!' So I would love it.

Willie Garson, Twitter, March 8, 2017:
A White Collar fan tweeted him "Please tell me there's more plans for White Collar? #mozzie"
To that Willie replied: "God I wish I could....."

Matt Bomer, USA Today, March 13, 2018:
"We talk about it, but it's kind of tricky. We were Fox Studios for USA Network (NBCUniversal), so it's two different entities to appease. But if they ever say, 'Matt, let's do a White Collar movie,' I would do it in a heartbeat."

Willie Garson, Twitter, March 14, 2018:
"I'm comfortable speaking for all us in saying we'd ALL be there in a heartbeat....unfortunately that's not how it works, nor do we have control over such things. I promise you all, we certainly wish we did."

Matt Bomer, Watch What Happens Live, June 14, 2018:
"I would love that. I would be there in a heartbeat. [...] I would be there with bells on."
