The 'Notorious,' who has picked up victories in three different weight classes, revealed that he wants to build a successful run at 155 pounds.
And McGregor is keen to emulate his success at 155 pounds as he did during his memorable run at featherweight when he shot to stardom.
The former two-division champ told TheMacLife: "I would like to put a stint in at 155 pounds, for sure.
"I came into the UFC as a featherweight and I went through the division. I gave it my all in that division and I tore through it like a chainsaw through butter. Interim title, then unified title.
"Then I went up and reached for greater heights, went to the lightweight division, became lightweight champion and became the first dual-weight champion in the company's history.
"Then obviously other things presented themselves, the Floyd [Mayweather] fight and where it went.
"Then I went to the welterweight division, also. I never got a good stint at 155 pounds, a consecutive stint like I've done in the featherweight division.
"I would like to do the same here in the lightweight division that I've done in the featherweight division: give it a good run and tear through the division.
"There's many good competitors, good fighters, in there, and I feel levels above them all. So, I would like to put that stint in."
UFC president Dana White has recently admitted that Diaz, who hasn't fought since his defeat to Jorge Masvidal at UFC 244 in 2019, is expected to make his return at lightweight.
And McGregor has suggested that the UFC is "dangling carrots" in front of him, adding that a third fight with Diaz is something he would love to do.
"There are dangling carrots [...] treasure chests that get presented to me," he continued.
"We've got world titles in boxing now, there's talks of [...] I hear Dana talking [about] Nate Diaz coming back down to lightweight. I love that. I'd love to compete against Diaz. We will compete again.
"If that happens at lightweight for a title, that would be something special, also.
"So, there's many great options that are in the works and let's see what happens. I am ready."
McGregor, who has previously welcomed a third fight with Diaz, suffered a shock defeat to the 'Stockton Slugger' at UFC 196 in March 2016.
However, the 'Notorious' avenged his defeat to Diaz only months later when they clashed at UFC 202 in Las Vegas.
McGregor has made it clear that he feels the 35-year-old American's first fight back at lightweight should be against him.
"I think if he's going to come down to 155, he should come down for me, to be honest with you," he said.
"Nate's a warrior, Nate's a go-er, Nate shows up, steps up and fights. It's not necessary, I don't feel, to have him fight another 155er against another contender. I feel maybe it should be me and Nate, you know.
"If it's going to be 155, we could possibly do that for the belt. If not, I'd probably just fight Nate at 170 pounds again. The reason being we fought at 170 twice. Why mix it up for the trilogy?
"But, if there's belts and titles and loftier things on the line, I'm certain a 155-pound challenge with Nate would be something. So, many great fights and many great options, and I'm pretty excited about every single one of them."
