Many things are wrong with PP10 and an All 5 Games speedrun and reasons why I wouldn't recommend it:

Dodo Re Mi:Only time you're technically playing the game but it's really just an autoscroller.

FixyText:Literally Devils and Details from PP7 but much worse(Aka 3 Rounds).

TEE KO 2,Timejinx, Hypnotorious:Spam Answers ASAP. That's all you need to do.

You may think that moderation can help me with these games. Here's the short answer:They don't. You can't do the strat from the first TEE KO Game, You can't skip anything, and you definitely cannot make FixyText any faster then it currently is.

I think PP10 is an okay pack, but as a speedrun, it's god awful other then Dodo Re Mi.
