Details

I am removing a load bearing wall in the second floor of my home. Looking for  structural designs that can be placed in the attic that will inversely support the span.
The house is:
-  Located in the NorthEast Part of the US. (think snow and ice)
- Balloon construction built in 1923 - all wood
-  16" 2"x6" rafters OC

Span 16'

Have a design that would require me to cut the rafters and add an 8"x8" beam plus add horizontal and vertical attachments to the 2x6 roof joists. Not happy with that design (see attachment). I do not know why the building inspector wanted 2x4 attached 1/3 and 2/3 on the roof rafters and the joists. (dropbox link)

Would like an alternate design NOT to cut the existing rafters. (see attachment)
Would like a alternate design using LVL or MicroV instead of wood beam. Cost is always an issue.

let me know if this is something you would be interested in completing.

The hand-drawn diagram came from the building inspector, as an example, so
I would need your structural engineering design load/spec that would exceed his idea.
I do not want to cut into the rafters/joists and insert a 8x8" x 24' beam....thus looking to you for a different design that exceeds his drawings, structurally.
Have additional design work - design 2nd floor balcony (6' by 25') with no ground supports (cantilever or cable/tie) to existing structure (adding 60" french doors)....same floor same room (north side).

Rafter -Material is from 1920's old wood (Georgia pine or some northeast tree).
They are cut a true/full 2"x6" at 16"OC
The ceiling (and walls) are hand troweled smooth plaster and lath. The lath are spaced about 1/4th inch apart. The plaster is a mixture of gypsum plaster and lime, and includes horse-hair (1st floor) and sand (1st and 2nd floor).
Attic is a light storage space. (HVAC ducts and some seasonal items). The largest item is when I am up there (250#).
I have not added insulation yet, as the HVAC was just done and I just removed all the knob and tube wiring.
I am looking for additional photos of the attic.
Attaching the inspection report in dropbox now

From your recommendations – would need additional structural (supporting docs/design) is it possible to have a structural analysis performed? Dynamic/static loads?
