HX40 flows a lot more than GT35, in truth HX35 is on a par with it and 60-1.
You can get T4 flange HX35, or at least you can buy bolt on housings. IIRC the smallest comes in at 19 CM^2; I asked Jaymez at Diesel Injection Service in Cinci about it once and that's what he came up with for me. I think that'd spool about like a GT35.

You can get a 16cm T4 flanged hot side. Now not stock on an hx35, but there were a few hx40's like that.
Here are some interesting things to note:
Hx-35
Specs:
Compressor cover- 4" intake and 2.5" out.
Compressor wheel - Inducer: 56mm, Exducer: 81.8mm
Turbine wheel - Inducer: 60mm, Exducer: 69mm
GT3582R
Compressor cover- 4" intake and 2.5" out.
Compressor wheel - Inducer: 61mm, Exducer: 82mm
Turbine wheel - Inducer: 62mm, Exducer
8
The imho the reason that the HX-35 makes power like the GT35 is 2 reasons
1) The big turbine wheel.
2) Higher efficiency at high boost
Now if you want the closest specs inducer to inducer an HX-40/35 hybrid would fit the bill.

Inducer vs inducer isn't a very fair comparison, especially since the Holset has a larger exducer meaning it's higher boost efficiency is through the roof.
Neither is turbine size a good comparison, exactly. It's a good indication of how much a turbo will choke an engine, but the HX35 spools a little better than a GT35 on the same engine.
There's a lot of good design on the Holsets. If they upped the inducer diameters to suit gasoline applications then they'd be true baller turbos.

I realize that inducer to inducer isn't even close to relevant, but it is a well published internet way of sizing things... 
If we want to complicate things further here are three different hx 40 compressor wheels.
Starting with the 8 blade compressor wheel
Then the 7 blade
Then the 6 blade
To make matters worse there are at least two turbine wheels for the hx40 as well, a standard 12 blade, and a higher flow 10 blade. I have specs for these at home, but alas I am at work... So if beer doesn't over take me I will post those up as well. :1
