Down to earth, Mr Malice and writing parts of the play

This year, the play is called Down To Earth, it tells the story of Sophie, a young scout girl who is recruited by some superheroes to help save the world, in the end act 2 (yet to be written) happens.

I have been chosen to help Diego write the play, the system is he writes a scene and sends it to me so that i add or correct things, the he checks it and turns in the final draft. The problem is that we write in very opposite ways, he tends to underwrite so to speak and i tend to overwrite, the play is supposed to be for children so we have to find a happy medium so that children and parents can enjoy the play.

Another problem is the input of the children who participate in the play, although i think it's very cool that the children's ideas are taken into consideration, some will be dissapointed because unfortunately, we can't write ALL of their ideas in and even if we do they won't be as spectacular as they want them to be because, well, the budget doesn't allow us to make a child dissolve into a black substance that creates fire wherever it goes...

so, how can we incorporate all the elements to get all the kids to be happy (remember, a happy worker is a good worker) without compromising the overall message and the play itself?

Mr. Malice
My character for the play this year is called Mr. Malice (frani's husband) and he's a villain, my power is karma inspired, whatever is done to me happens to frani and whatever happens to her happens to me, if frani dies i die. This is really great because Mrs malice and i have a disfunctional marriage, so when she hits me it hurts her too, this gives us plenty of things to do that could be very funny.
I still need to work on my character, i need to figure out what to do when i'm not saying anything and how to say things, what accent to have if i have any (i was thinking british, but, there are several brits in this play so i think i need to come up with something more original. I also need to work more with Frani since we are always together in the play we need to kind of rely on each other.
I think, since we have the whole karma thing going, working more with physical work would be very interesting and potentially quite funny.

My personality is yet to be defined, Mrs. Malice is crazy and bipolar, but i was thinking it would be very nice for us to complement each other in a disfunctional marriage way, when she's crazy i'm calm, when i'm crazy she's calm. I also came up with the concept of us being stepford-ish (not in a sense that we do as we are told but more of the overall feeling, unexpressive faces with fake smiles, cold, almost non-present but very present in a weird way because when i'm like that frani is going crazy and when she's like that i am, get it?), i know that the wives were the only ones that acted like that, but it would be nice for both of us to be, so that we create an uncomfortable but funny atmosphere with the audience and the characters around us.
