Sure you could - Provided you choose a short enough initial linear stroke.

Response to At twice the piston area, I don't think I could get the handle pushed in. n/t

With your piston area of 0.83sq_in, you'd get 25lbs of force at a pressure 30psig, which is a compression ratio of 3:1, or an initial stroke of about 5.67".

So possible geometry would be: 5.67" of linear stroke, followed by 2.83" of lever-assisted stroke, for a 3:1 improvement in leverage and mechanical advantage.
