Hipwood played his first game in 10 months on Saturday night after overcoming a ruptured ACL, gathering 11 disposals, including four goal assists, against Adelaide.
Now the 24-year-old is awaiting the return of Daniher (shoulder) and McStay (ankle) – a trio that helped Brisbane to a 10-1 win-loss record when they took the field together in 2021.
"I'm certainly excited and I'm sure we'll cause some havoc in the back half of the year if we can get back and play together," Hipwood said on Tuesday morning.
"I'm excited to play with them, they're both quality players, so it'll be good when we're all up and going."
Daniher was enjoying his best run of form since his All-Australian season in 2017 before hurting his shoulder against Sydney in round six, while McStay joined him on the sidelines a week later following a mishap against West Coast.
Daniher ran strongly at the Gabba during a light training session on Tuesday, while McStay jogged laps and then did some kicking on his right foot.
Neither joined in for any of the Lions' light drills, but both are expected to be available for selection in the next month.
Brisbane faces a selection dilemma when they're all available, with Oscar McInerney and Darcy Fort proving a terrific ruck combination – giving the Lions five tall options to choose from as forwards and rucks.
"I'm glad I'm not selecting the team," Hipwood said.
"It's going to be competitive for spots, and you need that as a top-four team.
"You need some other boys pushing you to get better to create a competitive environment.
"It's going to be good when everyone's fit."
