While my mind is absorbed with all things Force Ghostly and Force Lightningly (it must be a side effect of coming out of the Halloween season).
The whole idea of Palpatine waiting for Yoda to regain consciousness before continuing the fight and cackling like a loon is V Poor.
It might be possible to introduce a bit of ANH style spiritual guidance in the form of Qui-Gon's voice suggesting that Yoda drop to the floor before the lightning hits (so it misses him entirely).
Lucas already sampled one side of TPM's "Anakin drop!" for AOTC there's no reason beyond the technical why a fan editor couldn't sample the other half.
"My little green friend" is a cute line but trimming the little and green puts it more in line with how Palpatine speaks in ROTJ.
The Emperor's big blue friend is a bit surplus to requirements too.
I'm sure the scene would flow more quickly if he was removed from the room.
Taking the silliest cackles and the most acrobatic of fake leaping around from the sequence and it would be a bit more in keeping with the OT while still giving Yoda a display of the powers Luke will later be warned not to underestimate.
