I think it's unlikely as Lukashenko's army is probably even worse trained and equipped than Putin's, especially after having having transferred large quantities of what arms they possessed to Russia. Plus the Pripet Marshes are still there stretching westward from north northwest of Kiev to the Polish border, and the Ukes have been fortifying the northern approaches for months.
Lukashenko is buying time and sitting it out, running training exercises, like Franco in WWII.
