Monza will play their football in Italy's second tier next season as one of three clubs to move up following the premature end to the Serie C campaign alongside Vicenza and Reggina, due to the coronavirus outbreak.
Berlusconi, a four-time former Italian prime minister, took over Monza in 2018 -- a year after he sold Milan to Chinese businessman Li Yonghong -- and has big ambitions.
"Ibrahimovic and Kaka have been transfer targets for us and, for non-footballing reasons, we couldn't. But you never know," he told Telelombardia.
Berlusconi also said Monza, who were 16 points clear when the season was brought to a halt, are not simply content with staying in the second tier.
"I never had any doubts about it [being awarded promotion]," he told local newspaper Il Cittadino. "We started top, we stayed there until the postponement.
"Now we will set up a top team to play in [Serie B]. Promotion to Serie A depends on many factors, but we know some of them well and we'll do everything to exploit them."
Berlusconi, who is worth an estimated $5.8 billion and is a four-time former Italian prime minister, was Milan president from 1986 in 2017 and oversaw them win five European Cup/Champions League trophies.
He signed both Kaka, in 2003, and Ibrahimovic in 2010, for Milan with the pair winning Serie A titles in their maiden campaigns with the Rossoneri.
Italy's top two tiers, Serie A and Serie B, will re-commence on June 20, with the lower leagues having seen their 2019-20 campaigns cancelled.
