I like the idea of perhaps replacing the strings with piano.
When scoring this for a musical, you gotta think about the practicality of the pit. I do major broadway touring shows, and THEY are cutting back extensively.

Strings would be very difficult to get, and bad string players are worse than no string players.
Realistically, you could probably get 5 players. By far, the only instrument that actually matters is the piano, its the whole shebang in a show. The pianist is the musical director, the rehearsal pianist, the core of the pit. The other instruments are used as needed or afforded. There is also the space consideration when dealing with a pit, especially in a community theatre. Put a piano (doubling on keys), a drummer/percussionist, a bass down there and its most of the space. I once played Guys and Dolls, and as a violinist I had to play percussion on one tune.

Stuff like that is the key to making 4-5 people sound like 10.
At a local, city, community or even regional level, strings are almost unheard of. I did
Oliver! last summer, and it was for a pretty big place here. They couldnt recall ever using a string player. If you see the musical, you would realize that the violin has a part that cant be cut.
Yes the ending is awkward, what would be better a fade out?
Fade outs are hard to do live. I suggest just a simple, final chord that tells the audience that we are done with this song.
I would love to lose the hat, and consider it done. I would like to continue with something latin like congas and bongos, but my drum patterns are severely lacking.
The drummer is going to be too busy to play hi-hat. Hes going to be playing percussion on this one, and he cant do both.
I will be very curious to hear how this pans out. I'm a big fan of musicals and have played most of the standard rep. You would be surprised how small the pits can be. Parts like strings and winds are luxuries, and it has to be written in sich a way that they are expendable.
EDIT: none of this matters if you are planning to use a tape.
