Yes, it'd be possible, but it's not practical. You'd spend about twice as much (or more) as you would simply going single turbo to get that 500rwhp.

if I was to go with the 425-450 rwhp how much would it cost for the new turbo's, etc. that I would need to be brand new again?...

Last I recall, brand-new turbos from Toyota are about $2250 EACH, and a new shortblock is about $3,250 or so...

You'll need all the standard bpu stuff, plus an fmic, an aftermarket bov (recirc), adjustable cam gears, and a fuel controller. You'll need a spring on your wastegate, and you'll need to run about 25% race fuel to bump up the octane.
I've never bpu'd a Japanese-spec Mkiv myself. I believe you'll also need a speed limiter defensor. We may also need to find a way to get your downpipe connection made larger so you can run a full 3" US-spec downpipe.
