Does she have enough room? and does the first row have to be 12 feet back or can it be a little closer?
I think we need more information before any really productive suggestions can be made. A big unknown is the budget limitation, as well as performance expectations.
No sexism intended, but is Sis a A/V Enthusiast, or a 1st Timer looking for a good starter system. Ceiling Height is a critical measurement that is lacking...needed to determine what is and is not feasible on many fronts.
That said, a 24' deep x 14' wide space is very workable, if the right size screen in relation to 1st & 2nd row /Bar distances is chosen, and mated with the right Projector.
Items such as an Acoustic Screen set into a False Wall are a bit much for most beginners, and certainly add to the complexity and cost. The suggestion of In-Walls and a Acoustic Screen is a good starting point, and from there ......if desired, things can progress further.
I've worked up a hypothetical Floor Plan to let you see the type dimensions and distances your stated measurements can offer. I would offer a hypothetical list of Equipment, set at a lower Mid Tier as far as price and Performance....but that too might be presumptuously premature.
Still, the plan below allows for Floor Standing Mains...either a Wall mounted or In-Wall Center...4 Wall mounted or In-Wall Surrounds...2 Ceiling mounted Rear Surrounds...and 4 Atmos In-Ceiling. 4 THX-Ultra In-Wall Subs keep the floor space clean. 13 Channel Receivers are here and reasonably affordable. Here's the thing...your room is deep and your projecting seating space for anywhere between 12-16 humans. If any real funds are to be spent beyond the Image, it must be on the multi-channel sound.
.......and mentioning the Screen.....either a 120" x 50" 2.39:1 Mfg Screen, Solid surface or Acoustic...or a fully Painted "Non-Format" Screen Wall...screen size fully adjustable to the need at hand.
Projector? Well much now depends upon your feedback answers to the ist questions posed above.
