Plus they would have more cannon fodder to throw at Ukraine ... >

Belarus has nothing to offer in terms of war >

I don't know for sure, but they offer Russia 2 things.
1) More bodies to throw in the fire.
2) Some kind of made up legitimacy "look, another country doesn't like Ukraine, so we must be right" >

Army of Belarus is inept, badly trained and has weak morale. We will steamroall over everyone, who'll cross our border.
