Removing ceiling joists in old house

Im currently remodeling a small house (515 sq ft) that was built in the 1940s. Previous owner started the remodel, got bored with it and I ended up buying it. He was hanging drywall over drywall on the ceilings and I decided instead of finishing what he started, I would just start over. Now I have removed the ceiling to reveal the old rafters. They are 2x4s with 24inch spacing. The joists are also 2x4s spanning the width of the 11ft room.

For the sake of making the small house feel a little bigger can I remove the ceiling joist and add rafter ties higher up to raise the ceiling?

The ceiling joists are just resting on top of the walls, not connect to the rafters

Although it is small, 2x4's can't span 11 feet, so you are undersized at best. I would also consult with a structural engineer for the feasibility of removing the joists, which I doubt will be an option. Joists keep the side walls from bowing out, and it appears yours are stick built, so they may need to stay in place, IF not be reinforced with 2x6's at a minimum.

Its possible you could move the ceiling joists up a foot or so, but the existing rafters to top plate connections would need to be beefed up with rafter ties. Stepping up to 2x6 is advisable, as is seeking the blessing of a structural engineer and getting him to sign off on the plan.
