Warpspeed, of course not, lot's of things need to change. A 1000 rwhp 2JZGTE would need new cams, possibly better intake manifold, stronger rods & pistons, bigger injectors, etc, as would a 1UZ -and it should make 1000 rwhp with 30 psi. I think we are actually in agreement in some ways. If you left a 2UZ completely stock, slapped on a M112, then a very large turbo, perhaps you would need what you suggested. I made the assumption that the 2UZ would be modified quite a bit to accomodate the twin charging, with the very least: lower compression pistons, better rods, better intake (perhaps a 1998+ 1UZ intake mani), much better cams. I would personally want to start with a motor which, without the aid of SC or turbo, made at least 300 rwhp. That should be very reasonable with the right changes. Given that, I would expect getting to the 1000 rwhp mark could be achieved with around 30 psi intake manifold pressure, and perhaps around 20psi between the turbo compressure outlet and the SC let. Then again, even with a worked over 2UZ, perhaps a M112 is too small. If it is, don't band-aid it with a turbo which needs to have a very high pressure ratio. The whole point should be to have both chargers to not have a high pressure ratio, right?
