Expect well less than 450whp out of the 5830 turbo. A 6262 is almost a 500whp on race gas and big boost numbers.

I would expect some solid low 10s even out of a small trans build with just the rear engine.. the front engine may not be help you run much faster at a dragstrip unless you set that up with an even bigger turbo than the rear has....
I have made 580 crank HP on a 5830 at 54 psi of boost on a 2 cylinder 1.1 liter engine.
These turbo can make power past their rated chart when everything is perfect (tune, wastegate set up).

I'm sure I could squeeze 500whp with a good timing map, maxed out turbo and such.

But that turbo is on the shelf. A 6262 would be a much better turbo for Power but it would need a much higher stall and some boost off the line.
I want to keep things simple and share the load between the two engines.

If you think about it, each engine will have approximately 2400lbs to handle underway with equal traction. Once the rear hooks hard off the line most of the load goes to the rear engine. I want to the front to gradually come in to help the rear engine...

Yes, just the rear engine would work but it would be a drag only car. I really don't like rear/mid engine cars when the HP is very high. The front end becomes really light and it's not a good feeling.
