Holset noob here with a question.
Do the 9 cm and 12 cm hot side housings use the same turbine wheel?

Is your actual question "Do the HX35 and HY35 turbine housings interchange?"
Too much of a Holset noob to know Capt.
That said, it sounds like the right question.
I'm not really planning as much as I'm just looking at options at this point in time.
Thanx!
On a stock motor I couldn't imagine having a 12cm housing unless it was an automatic that was sprayed out of the hole and intended to be drag raced. Maybe with something that reved to 8000rpm, something with more displacement or really tight gearing.
The assumption on my part is that the twinscroll aspect of the housing would be utilized via a pulse paired header. At that point it should spool pretty well, IMO... you'd be talking about a turbo capable of close to 500whp at that point, so everything is relative. Admittedly, it'd probably be a bit of a dog with an undivided manifold though.
9cm2 = 0.65 A/R
12cm2 = 0.89 A/R
in intarweb folklore, anyway... but I reckon it to be pretty damn close.
