Well Night Raid only has 4 members and the revolutionary army might have some Teigu users but i think they are not on Night Raid Level
Well and the main goal is to kill the minister but even if Budo is not there anymore He still has Esdeath and the ultimate Teigu
Not to mention Cosmina who was said to become stronger than anyone in th world if she eats a lot and two Jaegers and two Wild Hunts and maybe other unknown Teigu users so the empire has better chances of win in my opinion
