Some extra incentive to make this happen is that mutants will eventually be introduced to the MCU, since as a result of Disney buying 20th Century Fox (now renamed 20th Century Studios), Marvel Studios finally has access to the X-Men property.
Details about how mutants will be handled in this franchise are still being kept tightly-guarded, but considering that Ursa was never featured in the Fox X-Men film series, it’d be cool if he could get some time to shine in the MCU in his bear form, especially if Russia decides to put together its own counterpart to the Avengers.
