Change your stack depth with #pragma comment(linker, "/STACK:<>")
Does not seem to simplify well though, but I really don't recommend solving 12-unknown-variable boolean expressions with VTIL. 😛

12 are too few.
Just like amd x64 : rax,rcx,rdx,rbx,rbp,rsi,rdi,r8,r9,r10,r11,r12,r13,r15,r16.
Do not consider memory variables,there are at least 15 registers.
from vtil-core.
Total number of possible variables != Average number of variables an expression depends on. Eitherway changing the stack depth will work fine for your case, if it does not simplify something let me know and I'll check it out.
