Yes, you can propose your own project idea.  The key thing is to find a
mentor who is willing to work with you.  You can do that on this mailing
list and #qemu IRC.

I don't know the state of i386 TCG but I suggest checking if there are
prerequisites for vmx/svm that are missing from QEMU.  You may find the
i386 TCG needs some improvements before it becomes possible to work on
vmx/svm itself.  I don't know the answer but you'll need to check this
to see if your project idea is viable.
