I've just bought some poverty Pork…

Standard sizes are
205 50 17 front
255 40 17 rear
That is a lot of rear tyre and the same sizes [front and back] as the 911 or 996 - which I have and I daily. Now you could argue the 911 needs the big rear as its rear engined. In the Boxster it just leads to understeer - which you get in the 996 too but its expected with the rear engine.
If you like the feel of the car as is then dont change it.
I'd just buy whatever modern rubber you want.
If you were going to alter widths I'd go smaller on the back. A wider front is meant to dull the steering feel. You cant go wider on the front really because of the width of the wheel. Well you can if you want but its less than optimal.
Going thinner on the back is fine. Porsche recommend a 225 45 17 on the rear for winter use. I'd try that myself.
Or you could go 235 45 17 which will fit fine and will give you the same 205 : 235 of the 987 setup.
Just some thoughts.

225 on the standard 7inch front wheel works fine on a Boxster - no rub, correct rolling radius etc. It cured the understeer on track HOWEVER if I were to do it again, I would go LESS rubber on the rear not MORE on the front.
The limits are already high enough, and the larger front tyre did numb the steering off a little (Yoko Advan V105s).

Some of the USA guys run 225 on all 4 corners for those test events where they drive round cones and what not. So I'd be tempted to say go 205 on all 4 corners for road use. That probably means buying 2 more front wheels so requires some investment.
I have 2 sets of wheels for my 996 so I wanna try 4 fronts with 205 on all 4 corners. I'm just a bit worried about tyre pressures as the car is obviously heavier at the back.

I have flirted with the idea of fitting the 2.7 986 brakes to my 996 so I could use the 16 wheels but its doesn't sound simple.
You read like an accident waiting to happen.If you have a reason to doubt the wisdom of someone's course of action, then you can give your view, rather than post negative assertions framed in provocative language.

I don't think that would be a good idea. It's a 300bhp car, please don't reduce its stopping power. Also you'd need to tell your insurance company, and I don't think they'd think it's a great idea eitherIt might sound crazy but I wouldn't call it dangerous. There are people driving around in 3.4 originally 2.5 Boxsters on 2.5 brakes. People driving TPC turbo'd Boxster/Cayman S with approaching 400bhp and upwards on standard brakes which are the same as a 996 Carrera. People driving turbo engine transplants with standard sized brakes.

Looking into Caymans in the 20-20k range to see what's about, I have a question about driver size though, SWMBO is a petite 4'11" tall, is she going to be able to drive a Cayman?
My Mrs is just about 5ft and manages our 987.1 Cayman quite well. I doubt your missis will struggle. 
Then to match your lightweight wheels and brakes, fit a 1.6 k series engine. Then you've got the car it sounds like you'd all prefer.
Or alternatively, just buy a Lotus Elise and throw 3 cow hides at the interior so it's posh.
I don't get the whole balloon tyre thing, it's a sports car, sounds like you want it to ride like a 70's Rolls Royce.
