... no, just no.
The gap between him and Dooku is not that big. The gap between him and Maul wasn't that big. Heck, the gap between him and Fisto wasn't that big, Fisto was able to react, and I refuse to believe Kit Fisto is > Darth Tyrannus.
Grievous is easy to take out - no telekinetic defence and vital organs that can be crushed on whim.
Again, Dooku gets to set the plan. So they can minimize opportunity of that/make sure if it happens, Dooku should be in position to take advantage of that distracting whim.
Then Dooku can basically be wiped out through the Force or in a duel... I can't think of a plan where the team could plausibly win this,
Well, that's because you're letting Sidious pick who he engages in what order, when the scenario is the opposite.
Lesse, if I were Dooku... I'd send in 2 waves of droids (say, 3 battle and 3 magna, battle positioned as shields to give the magna slightly more survival time, then another wave of the same thing), which gets sabered and force-smashed of course, this is just a warmup/to get him to spend a little effort, then Dooku engages, then Grievous and the remaining droids jump in while he's already got a Dooku to deal with, ready to take advantage of distractions. Then, sure, Sidious will be using the force to take out each of the four remaining magna and Grievous, in turn, but each force attack gives more opportunity for everyone else to attack. Crush Grievous's organs and that's when Dooku + whatever Magnas survive attacking at full.
Finally, you have the remaining Battledroids positioned at the door of the room, if Sidious manages to get disarmed at some point- something that has happened to him before- their instruction is to hose him down.
