Not fair to spoil exectations, but i'm here again with some news. New USER salvation is delayed due to my work on KernelEx 4 (finally) as well as other busy things. The news, i've figured out how to theoretically implement GDI heap expander without breaking compatibility, performance and memory usage. This includes a lot of things to hax: global memory manager, local heap handle manager and GDI insides, but seems possible unless I bump into hard compatibility problems. But theoretically, it can be very-very promising; i won't spoil numbers. Or did rloew already implemented one?
