McCoist has made landing a centre-half his main priority after agreeing deals for seven other new players ahead of the 2013/14 season.
He has already held talks with Berra about coming to Ibrox after he was released by Wolverhampton Wanderers following their relegation to League One.
The former Hearts player moved to Molineux from Tynecastle in February 2009 and made 154 appearances for Wolves, including 64 in the Premier League over two seasons.
Berra, 27, is a free agent having moved south of the border for £2.5m from Tynecastle four years ago.
McCoist, who expects Honduran midfielder Arnold Peralta to arrive in Scotland next week after a holiday, said: "Without doubt, Christophe is someone I'm looking at.
"He's a player I would think ticks the vast majority of the boxes. He's a great age, a good player and he has vast experience."
Bosnia's Pandza, 26, who most recently turned out for Belgian side Mechelen has been capped 22 times by his country.
McCoist added: "Boris has come to our attention too and my chief Bosnian scout Sasa Papac, who I talk to on a regular basis, speaks highly of him.
"They are both from Mostar so they know each other pretty well and Sasa has given him a glowing report."
But of former Rangers star Novo, 34, who left Ibrox to return home to Spain at Sporting Gijon in August 2010, he revealed: "I've got to be honest and say we've signed a couple of centre forwards and our priority is getting a centre back.
"In that sense we'll see what happens. There's nothing in it at the moment and he's just coming in to train and enjoying himself with the lads."
