Is it possible to position yourself correctly and safely in the slot for FP while using the old baloon-style chest protector? Or is it a bad idea?

I don't know if it is possible, but IMO, it is a bad idea, for looks if nothing else. I entered umpiring when the ASA FP uniform required an inside protector, so I've never used one.

Personally, to me they look like a character out of a Normal Rockwell cartoon! ;)

I used to use a "raft" for baseball and sometimes
men's fast pitch. It was not a baloon filled with air
but a impact absorbing foam material.
I loved it. I'm a big guy 6'3" 275 and I sweat like
a stuck pig with an inside protector. I never had a
problem with it--learned how to wield it w/o any
complications.
And it worked !!!
Since going to an inside protector I've taken numerous
hits and dings to my wrists, elbows, and fingers--
something that never happened with my raft !!
I think it would be a great option for umpires with
injuries or very vulnerable body parts.
Just sayin'

That's exactly why I'm considering using the outside protector. It sure looks like thighs, arms, and hands are right out in the open when the inside protector is used. I don't care what I look like - as long as I can call the game accurately, and efficiently, then safety wins out, IMO. In fact, I think I'd be a better ump, that is, if I did not have to even think about getting hit.

I own a balloon protector but have actually never used it in anything other than a practice game.

I'll have to say, the level of protection is VASTLY higher with a balloon protector. Every part of your body that is typically exposed or minimally covered when using an inside protector is COMPLETELY covered.

You won't take any shots on the arm, collar bone, or shoulder. Even those little tips that strike you directly in the heart of your chest protector are not as painful since a balloon protector is much more substantial and absorbs the shock much better.

The only reason I don't use the balloon protector in actual games is ...
1. It's different. Nobody sees those protectors any more and I have no desire to be the "bearded lady" at the circus.

2. It's more cumbersome with regards to having to signal and operate the indicator. In other words, it's just another thing to hold on to.
