Anyone put the old Lloyd titan mech head on the new one yet?

I really dig the new Lloyd Titan mech and want to grab it pretty soon. The only thing I'm not liking on it is the new head, which looks too small. In contrast, the original Titan Mech's head looks like it would be perfect in terms of proportions. To the point where I'm considering to buy the parts just for the old head and adapting the joint structure.

Has anyone already given it a shot to switch the heads out?
