could you install a bladder onto gas post and pump air in to maintain pressure?

Free gas. 18 litre corny fill instead of 19?

Oo I like that, properly outside the box thinking.

Yup. Use cheapo bread yeast, make as much as the cylinder will hold. Prolly a 4litre brew. That could work.
I like people that are willing to try ideas out to see if they work and admire your willingness to give it a go @MashBag but ...
that being said make sure you keep us updated if you do decide to go for it 
Is there nowhere local that you can get a cylinder without an ongoing rental? I paid a deposit and the about £20 for a refill which lasts me over a year
... I can't help feeling that it sounds more of a faff than just using a cylinder

I have got one.. And prolly a local supplier. Just think, when prefected, this might be better. Wish me luck.
I've found that if I completely fill a Corny with 19L of beer, it's as flat as a fart, because as hard as I try, I can't get it to hold gas. I've shaken it, rolled it about, even played catch.
If you like that thing, great.

What about a mylar balloon to collect, and then a pump (compressor) to pressurise it into a keg?
Are mylar balloons food safe?

@Buffers brewery
How about a 20l wine bag inside corny.
Bag - tap adaptor connected to gas post, hand pump air.
My first thought is this might trap beer above the bag.
Messy solution I think?

A couple of things here. Firstly, farts aren't flat, what with them being made up almost entirely* of gas.
Secondly, I've never found the shaking or rolling method of carbonation to be either effective or accurate. Either does nothing or ends up over carbonated. Best way I've found is the fire and forget method, set it to serving pressure and leave for a week.
Thirdly, As said above, you've got a leak somewhere. Replace your seals and even the posts. Cheap to do.
*We won't discuss the alternatives here.

I wonder if I should leave a bit of headspace? I have a habit of filling my cornys to the top, and there's nowhere to actually store much gas.
So as I drink it, it gets more carbonated. Does that make sense?

Interesting, to think about alternative methods.
What about having some kind of tube / stand pipe, inside the keg, that releases priming sugar solution as the beer level drops.
Pipe sealed at bottom end except for a small hole, maybe 1mm diameter. Something just big enough to allow sugar solution to pass as level drops, but too small to allow significant mixing by diffusion.
Not sure of the keg internal diameter, but if dispensing a pint (570ml), caused beer level to drop by say 10mm. Then you'd need a priming tube diameter, that would depend on sugar solution concentration, to contain in a 10mm length, the sugar equating to 570ml CO2.

Just finished an (almost standard) pressure barrel, of Heffweizen. Without any CO2 (S30) topups, the last pint still came out with head that half filled the glass.
Using top tap barrels, with an extra rubber on release. As a single rubber, seems to release at too low a pressure.
Started with around 19l in the barrel. Rrest of the 23l batch, being bottled, after priming whole batch with 125g sugar in solution.
For some reason, carbonation in the one bottle tried so far, was much poorer than from the barrel.
I always find, that more initial headspace, means more beer is dispensed. Before CO2 top-up is needed.
