If your problem is the 68000 and WHDLoad because of the QUIT key, then Jens has said that his card would intercept that (whatever it is) and allow it to quit.
(I'm pretty sure anyway, that thread is huge and I can't find it now with a quick browse)

The quit key can even be implemented on a stock a500, but you would need to replace the vector table at the end of the kickstart rom.
I think figuring this out was the reason why the 020 was dropped.
Would 14mhz display a lets say s letter drawer full of games that much quicker to justify this expense?
Buy one and try it. Your question is too vague, how much quicker does it need to be to justify the cost? That isn't the main reason to buy one of these anyway.
You need to have an external CPU for the external kickstart loading to work.
It has to be fitted inside like the first prototype.
That statement is provably wrong. Jens says he had to make it external, I prefer it.
However there is no reason why you can't just hack in an 86 pin connector inside your A500. It will involve doing some major DIY, remove shielding etc & probably remove any other internal expansions but if you want to do it then go for it. You might have problems attaching something to the real 86 pin connector, but if you want it to be internal then it's unlikely you've got anything on there anyway.
There are loads of things you could add to a wish list for something like this, but ultimately it's an A500 and certain upgrades are pretty pointless. You could put an 060 in it, but what are you going to run?
